9d7c1947f5 [DevTools] Add V8InspectorSession::state(), which returns binary (CBOR).
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).

8665bac17a Revert "inspector: teach v8Inspector to return default context"
This reverts commit 22cb8d45c3.

Reason for revert: it is fundamentally wrong to fetch default
frame context using contextGroupId: contextGroupId is per page rather
then per frame.

dbfcc4878a [inspector] added V8InspectorClient::resourceNameToUrl
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.

885a5669aa Reland [inspector] introduced stackTraceId and externalAsyncTask API
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.

81b7e77ff0 [inspector] Build inspector under v8_enable_inspector build flag.
- inspector becomes a dependency of v8_base;
- generated public protocol files are placed to gen/v8/include/inspector/<Domain.h>;
- added v8_enable_inspector_override to be used in embedders (gn only);
- combined public headers into v8-inspector.h and v8-inspector-protocol.h.
