Now that we have a suitable composition recorder infrastructure, it is just a
matter of plumbing the `WebRenderCompositionRecorder` from the
`CompositorBridgeParent` to the `RenderThread` to start recording frames.

Since WebRender does its rendering on a separate thread from the compositor
thread, we need a composition recorder that can be shared between threads.

The AsyncScreenshotGrabber now can operate in two modes:
* `ProfilerScreenshots`, which does asynchronous scaling of the captured frames
for inclusion in profiles by the Gecko Profiler; and
* `CompositionRecorder`, which does not do any scaling and is used for visual
metrics computations.
The latter mode is exposed by on the `Renderer` via the `record_frame`,
`map_recorded_frame`, and `release_composition_recorder_structures` methods.
A different handle type (`RecordedFrameHandle`) is returned and consumed by
these functions, but they translate between `RecordedFrameHandle` and
`AsyncScreenshotHandle` when communicating with the underlying
`AsyncScreenshotGrabber`.
I considered making the `AsyncScreenshotGrabber` generic over its handle type,
but the extra cost of monomorphization just to change the handle type did not
seem worth it.

The CompositionRecorder was being stored as a UniquePtr on the
CompositorBridgeParent, but was then passed to and stored on the LayerManger as
a raw pointer. This has been updated to use a RefPtr.

The `WebProgressChild` no longer sends a `matchedList` parameter in its JSON
messages to the `RemoteWebProgress`, so it will always be undefined and trigger
a `ReferenceError`.

The WebRenderBridgeChild now records whether or not it was painting content
while sending display lists to the WebRenderBridgeParent, allowing for
composition times to be recorded for WebRender.

Previously the end of JumpList's link is marked by `offset + delta == -1`,
BytecodeOffset class introcuced in part 3 requires the operands of `-` operator
should be valid, and that rule conflicts with above.
Changed the end marker of JumpList to `delta == 0`, that won't happen in other
case, because that points the same opcode.

Previously the initial value of BytecodeSection.lastTarget_ is chosen to make
the following condition true:
lastTargetOffset() + ptrdiff_t(JSOP_JUMPTARGET_LENGTH) == -1
BytecodeOffset class introcuced in part 3 requires the offset value to be
either -1 (invalid) or non-negative, and that rule conflicts with above.
Changed the initial value of BytecodeSection.lastTarget_ to -1 and added
the check for that condition in BytecodeSection::lastOpcodeIsJumpTarget,
so that we don't use negative value in BytecodeOffset.

Classes defined in JS using the `class` keyword, without using `extends`,
implicitly construct a new `this` object before running the body of the
constructor, and they use `new.target.prototype` as the new object's
[[Prototype]]. This is one of the ways that JS classes support subclassing.
When the subclass calls the base class constructor, the subclass's `.prototype`
is used.
Until now, we did not do this for classes defined in C++ using
JS_NewObjectForConstructor. But there's no reason it shouldn't work the same
way. Changing this is a nicety for embedders -- there's nothing using it in
Firefox or internally right now, except for testing.

I think this is a good change regardless of other discussion in bug 1552587. If
we decide to move `mColor` to the top-level of the struct that can be done
separately.

This is similar to this Chromium change:
https://codereview.chromium.org/1155353002
The editing spec doesn't mention editing non-HTML documents, and historically
this is only a feature that WebKit has supported. Supporting this feature
increases the attack surface of the browser without a clear benefit, so it
seems like a good idea to converge on this behaviour.
