In most situations, JSONWriter users already know string lengths (either directly, or through `nsCString` and friends), so we should keep this information through JSONWriter and not recompute it again.
This also allows using JSONWriter with sub-strings (e.g., from a bigger buffer), without having to create null-terminated strings.
Public JSONWriter functions have overloads that accept literal strings.

This patch uses IPDL's return feature to ensure that the memory
reporter manager won't wait for a report from a child process
that has already exited.
This fixes a memory reporter hang that can happen if a child process
exits during a memory report, when the parent half of the actor is
being held alive. (If the parent half of the actor is not being held
alive, then mMemoryReportRequest will be naturally cleared when it
goes away.)
This was happening frequently on Windows Fission AWSY because that test
does a minimize memory right before it attempts to get a memory report,
and the preallocated content process exits when it sees a message to
minimize memory.

The next patch converts the memory reporting architecture to use the "returns"
feature of IPDL, and mozilla::ipc::RejectCallback does not have a return
type, so this patch removes the return value.
FinishReportingCallback::Callback() needs to remain an XPCOM method
that returns NS_OK because it is called from JS during testing.

Clamp the requested XRWebGLLayer framebuffer size to ensure it's not too small to see or larger than the max native resolution.

With these changes, on my Linux analysis with ClangBuildAnalyzer, the
top two expensive headers, DOMTypes.h and TabMessageUtils.h are no longer
among the 30 most expensive headers.

The logic was apparently initially copied from the compositor thread which too got migrated to nsThread in bug 1634253, so we re-use that same logic again.
This allows to remove all use of the Google's MessageLoop.

In all those cases, the current nsISerialEventTarget is either the main thread or the MessageChannel's nsISerialEventTarget (since bug 1634846)

We are here, always actually dealing with the compositor thread, with the exception of VRDisplayPresentation which is passing the main thread.

- Enable WebGL SwapChain pooling on Android. Creating and releasing Android Surfaces every frame causes a big performance hit due to AndroidSurface slow destructors bug.
- Add a separate SwapChain for WebVR. We are already using separate SwapChains for WebXR (WebGLFramebuffer::mOpaqueSwapChain) but not for WebVR (it uses the canvas backbuffer).

In this bug we're moving away from monolithic JNI headers to class-specific
headers so that we don't have to rebuild the world every time we make a change
to a JNI interface.

Gecko Idle detection relies heavily on RefreshDriver. GC/CC scheduling, including when to run GC or CC slices, and the length of the slices, is mostly based on idle time. As WebXR isn't using normal RefreshDriver, the content process thinks it's idle and GC and CC get basically up to 50 ms slices.
Not having WebXR idle detection is causing stutter frames during immersive presentation. This patch implements idle deadline hint and sets the correct GC slices budgets during WebXR presentation.

WebVR and WebXR gamepad pose data is updated after the RAF and not before. This adds a extra frame of latency for the input because JavaScript will not use the latest value.
