Make some methods on V8DebuggerScript virtual and provide the
implementations ActualScript for scripts which are backed by scripts on
V8's side, and WasmVirtualScript for wasm scripts.
The added test case ensures that we at least don't crash on the attempt
to get breakable locations for wasm "scripts", which we did previously.
Returning a reasonable result for wasm will be implemented in a
follow-up commit.

It turns out that showing a five-digit number of resources blocks the
UI for a few minutes, and it remains very laggy even after that.
This CL adds another component to the path of wasm scripts if the
module contains more than 300 functions. The additional component will
be the function index rounded down to the next multiple of 100.
Example URL before:
wasm://wasm/wasm-0284f1c6/wasm-0284f1c6-26337
Example URL after:
wasm://wasm/wasm-0284f1c6/26300/wasm-0284f1c6-26337
This avoids showing a five-digit number of entries in the resources view.

*and* report all "virtual" wasm scripts right when the wasm script is
registered at the inspector.
WasmScript is a subtype of Script, with the cast checking that it is
actually a wasm script.
This layout makes it quite easy to implement functionality that is only
available for wasm scripts, and allows to later directly use the
WasmCompiledModule instead of the i::Script for backing the
debug::WasmScript. We might also add virtual methods to
provide different implementations for GetSourcePosition, Source and
others.
DisassembleWasmFunction now also becomes a method of this class instead
of a static function on the DebugInterface.
The WasmTranslation now uses the new WasmScript type instead of the
Script wrapper, and also registers all virtual wasm scripts immediately
when the wasm script is made public to the inspector (when the wasm
module is created).

This CL adds a new header src/debug/interface-types.h, moves the
definition of Location from the debug-interface.h to this new header,
and adds a new definition for the WasmDisassembly types.
This allows to use the types in other implementation files or headers
without having to include the entire debug-interface.h, reducing build
dependencies and compile time (especially for incremental builds).
The WasmDisassembly type replaces the old
std::pair<std::string, std::vector<std::tuple<...>>>, which was a bit
hard to unravel.

The ScriptBreakpoint struct was before just holding line, column and
condition. It now additionally holds the scriptId.
This encapsulates information nicer, and allows for easier translation
of wasm locations, since one struct now holds all information needed
for the translation.

This CL further extends the debug wrapper, migrates around 60 tests, and
removes a few tests that use functionality we will not support anymore.
In more detail:
* Removed tests that use:
* enable/disable individual breakpoints
* invocationText()
* the ScriptCollected event
* showBreakPoints
* evalFromScript (and similar)
* mirror.constructedBy and mirror.referencedBy
* event_data.promise()
* Some frame.evaluate uses were adapted since due to differences between
remote objects (inspector) and mirrors. For instance, exceptions are
currently not recreated exactly, since the inspector protocol does not
give us the stack and message separately. Other objects (such as
'this' in debug-evaluate-receiver-before-super) need to be explicitly
converted to a string before the test works correctly.
* Ensure that inspector stores the script before sending ScriptParsed and
ScriptFailedToParse events in order to be able to use the script from
within those events.
* Better remote object reconstruction (e.g. for undefined and arrays).
* New functionality in wrapper:
* debuggerFlags().breakPointsActive.setValue()
* scripts()
* execState.setVariableValue()
* execState.scopeObject().value()
* execState.scopeObject().property()
* execState.frame().allScopes()
* eventData.exception()
* eventData.script()
* setBreakPointsActive()

This CL defines move semantics for String16, and fixes issues with the
hash code not being set correctly on swap or copy.
It also extends the interface by a few handy templates.
All this functionality will be used for the wasm translations, where
String16s are often concatenated and used as keys in hash tables.

Before, we allocated one script per function per instance, and each
script referenced the wasm instance and the function index. Now we only
allocate one script per compiled wasm module, so the script also only
references this WasmCompiledModule, which causes changes to many interfaces.
Instead of fixing the disassemble API only used via debug.js, I decided
to drop it for now. Some later CL will reintroduce it via
DebugInterface.

When Chromium and V8 use the same version of inspector_protocol, any protocol change takes at least 4 patches and 3 waiting for rolls.
To simplify this process we need to have two diffrent versions of inspector_protocol in Chromium and V8. Current state of inspector_protocol was extracted into separate repository [1]. This CL puts last version of inspector_protocol into third_party/inspector_protocol and removes dependency on inspector_protocol in Webkit.
