This introduces a `V8InspectorClient::dispatchError()` callback that
embedders can use to dispatch errors from scripts injected by DevTools
(via debug evaluate). The idea here being that while these errors are
technically caught by the inspector logic, the DevTools UX presents them
just like other uncaught errors, with the exception that they don't
trigger error handlers installed by the page. The latter can be quite
confusing to developers, and surprising when for example testing these
error handlers from DevTools. So this adds the foundations on the V8
side to enable triggering error handlers for these technically caught,
but morally uncaught, exceptions.
On the Chromium side https://crrev.com/c/3560458 will implement and
use the hook. And that CL also adds a web tests to check the behavior.

This moves every single class/function out of include/v8.h into a
separate header in include/, which v8.h then includes so that
externally nothing appears to have changed.
Every include of v8.h from inside v8 has been changed to a more
fine-grained include.
Previously inline functions defined at the bottom of v8.h would call
private non-inline functions in the V8 class. Since that class is now
in v8-initialization.h and is rarely included (as that would create
dependency cycles), this is not possible and so those methods have been
moved out of the V8 class into the namespace v8::api_internal.
None of the previous files in include/ now #include v8.h, which means
if embedders were relying on this transitive dependency then it will
give compile failures.
v8-inspector.h does depend on v8-scripts.h for the time being to ensure
that Chrome continue to compile but that change will be reverted once

Within the inspector we should be consistent about passing the script ID
always as integer, and only convert to String16 when actually needed.
That (a) saves memory (and some runtime overhead) when stashing away
call frames, for example in case of async stack traces, and (b) reduces
confusion which representation to chose.

Until now, the description for Nodes and Trusted Types was generated by V8 what was problematic, since Blink (not V8) is who has access to the information required for the description.
Once the refactoring is complete the existing descriptionForNode and descriptionForTrustedType can be deleted from V8.

A StringView is pretty light, so this should be similar to
how absl::string_view is typically used, e.g. see the guidance here:
https://github.com/abseil/abseil-cpp/blob/master/absl/strings/string_view.h
I suspect this reasoning holds even though StringView (defined
just above StringBuffer in v8-inspector.h) carries an additional bool.
This yields a small simplification of the StringBuffer implementations.

This CL implements functionality to allow an embedder to mark a
debug scope as terminate-on-resume. This results in a termination
exception when that debug scope is left and execution is resumed.
Execution of JavaScript remains possible after a debug scope is
marked as terminate-on-resume (but before execution of the paused
code resumes).
This is used by blink to correctly prevent resuming JavaScript
execution upon reload while being paused at a breakpoint.
This is important for handling reloads while paused at a breakpoint
in blink. The resume command terminates blink's nested message loop
that is used while to keep the frame responsive while the debugger
is paused. But if a reload is triggered while execution is paused
on a breakpoint, but before execution is actually resumed from the
breakpoint (that means before returning into the V8 JavaScript
frames that are paused on the stack below the C++ frames that belong
to the nested message loop), we re-enter V8 to do tear-down actions
of the old frame. In this case Runtime.terminateExecution() cannot be
used before Debugger.resume(), because the tear-down actions that
re-enter V8 would trigger the termination exception and crash the
browser (because the browser expected the tear-down to succeed).
Hence we introduce this flag on V8 that says: It is OK if someone
re-enters V8 (to execute JS), but upon resuming from the breakpoint
(i.e. returning to the paused frames that are on the stack below),
generate a termination exception.
We deliberated adding a corresponding logic on the blink side (instead
of V8) but we think this is the simplest solution.

This CL adds a new event that enables the back-end to send coverage
updates on its own initiative. This event can be triggered via the C++
method `triggerPreciseCoverageDeltaUpdate` on the agent in a way that
causes coverage data to be immediatelly collected.
This is useful in the back-end to collect coverage at a certain point
in time, i.e. when a lifecycle event such as first contentful paint
occurs.
The previous interface could not support this, because it could not
reasonably be triggered from C++, and if triggered through the protocol,
dispatching messages added delay that invalidated the data (i.e. data
might have been taken too late to be accurate).

The main change here is that in isolate-data.h, I'm switching from stateJSON to state.
This routine returns a CBOR encoded state cookie, which is also what we already
use in Chromium (blink).
In inspector-test.cc, I then put this byte vector into a V8 String,
and to make this roundtrip, change the extraction routine to get the
bytes. It's a little weird to store arbitrary bytes inside a v8 string,
but it appears to work fine because these bytes end up in the 8 bit portion,
much like isolatin characters would.

Keep the existing method for compatibility, by converting
to json from CBOR using the inspector_protocol_encoding library,
via a v8 specific interface library that directs routines for
converting between strings and doubles to v8's implementations.
This change also brings in the encoding.h / encoding.cc files from the
upstream inspector_protocol project. The only modification here
are the header guards, and the namespace. I will fix roll.py to
make it so that we pick up future changes.
third_party/inspector_protocol/BUILD.gn is specific to v8, by necessity.
third_party/inspector_protocol/.clang-format is a copy of the upstream
file. If we don't put this, we'll find ourselves auto-formatting the roll,
which is annoying.
This is a reland of
https://chromium-review.googlesource.com/c/v8/v8/+/1590627 with the
only modification in the DEPS file; this time I'm including
third_party/inspector_protocol/encoding/encoding{.h,cc} in addition to
the relative include there. Not sure why this is needed but I'm hoping
it gets me past the presubmit which may resolve the include path
relative to the V8 base (the ../../third_party is needed for when V8 is
embedded into Chromium).

Some clients (see Node.js) use platform path as ScriptOrigin.
Reporting platform path in protocol makes using protocol much harder.
This CL introduced V8InspectorClient::resourceNameToUrl method that
is called for any reported using protocol url.
V8Inspector uses url internally as well so protocol client may generate
pattern for blackboxing with file urls only and does not need to build
complicated regexp that covers files urls and platform paths on
different platforms.

Sometimes we need to capture stack trace on one debugger and use it
later as a parent stack on another debugger (e.g. worker.postMessage).
This CL includes following addition to our protocol and v8-inspector.h:
- added Runtime.StackTraceId, this id represents stack trace captured
on debugger with given id,
- protocol client can fetch Runtime.StackTrace by
Runtime.StacKTraceId using Debugger.getStackTrace method,
- externalParent field is added to Debugger.paused event, it may
contain external parent stack trace,
- V8Inspector::storeCurrentStackTrace captures current stack trace
and returns V8StackTraceId for embedder this id can be used as
argument for V8Inspector::externalAsyncTaskStarted and
V8Inspector::externalAsyncTaskFinished method. Any async stack
trace captured between these calls will get passed external stack
trace as external parent. These methods are designed to be called
on different debuggers. If async task is scheduled and started on
one debugger user should continue to use asyncTask* API,
- Debugger.enable methods returns unique debuggerId.
