This patch removes checking of all the callback calls in memory reporter
CollectReport() functions, because it's not useful.
The patch also does some associated clean-up.
- Replaces some uses of nsIMemoryReporterCallback with the preferred
nsIHandleReportCallback typedef.
- Replaces aCallback/aCb/aClosure with aHandleRepor/aData for CollectReports()
parameter names, for consistency.
- Adds MOZ_MUST_USE/[must_use] in a few places in nsIMemoryReporter.idl.
- Uses the MOZ_COLLECT_REPORT macro in all suitable places.
Overall the patch reduces code size by ~300 lines and reduces the size of
libxul by about 37 KiB on my Linux64 builds.

Avoiding these re-scrolls prevents APZ repaint requests from clobbering the
main-thread scroll position (which may have changed in the meantime) in some
cases. See https://bugzilla.mozilla.org/show_bug.cgi?id=1286179#c8 for an example
of a scenario where this re-scroll is problematic.

Previously we weren't sending scroll position updates with origin nsGkAtoms::restore
over to the APZ at all, on the assumption that they should never clobber an APZ
scroll offset. However, there are scenarios where that is not true.
In particular, during a frame reconstruction, a layers update may be sent to the
compositor between the time a scrollframe has RestoreState() called on it, and
the time the scrollframe has ScrollToRestoredPosition() called on it. The layers
update that happens during this interval (correctly) sends a scroll position of
(0,0), and forces the APZ to scroll to that position. This is necessary to
prevent APZ from remaining at an invalid scroll offset while the frame is still
being rebuilt.
However, once ScrollToRestoredPosition() is called and the old scroll offset is
restored, that restored scroll position needs to get sent to the APZ in order to
have it properly restore to the original scroll position. In order to do this,
the main thread must flag the metrics with a scroll offset update. Since the user
may have scrolled concurrently in the compositor from the (0,0) position, we also
need to check for that case in the APZ code and avoid restoring the scroll
position. This is equivalent to the corresponding main-thread code in
ScrollToRestoredPosition().

Implement a new OnFrameAvailableListener callback system for
AndroidSurfaceTexture using native methods. Each AndroidSurfaceTexture
creates its own SurfaceTextureListener object and uses it to forward
OnFrameAvailableListener callbacks to the corresponding nsIRunnable.
