Bug 1712928 - Gather telemetry about encoding-unlabeled pages and about Repair Text Encoding usage situations. r=emk

In particular, gather telemetry to evaluate the impact of unlabeled UTF-8
and how detector-triggered reloads would change if ASCII-only at initial
guess was treated as UTF-8.

Bug 1674776 - Update DocumentTimeline::mLastRefreshDriverTime outside parallel styling. r=boris,decoder

Note that we can probably use mLastRefreshDriverTime directly in
DocumentTimeline::GetCurrentTimeStamp(), i.e. we don't need to use the refresh
driver there, but I'd preserve the current behavior.

Bug 1761804: Remove checks for NS_COORD_IS_FLOAT, and its associated VERIFY_COORD() function. r=jrmuizel

This patch just assumes NS_COORD_IS_FLOAT is undefined (which in practice it
always is), and deletes dead code accordingly.

It's unlikely we'll migrate nscoord to float anytime soon, so this code isn't
serving much of a purpose at this point.  If we do someday make that migration,
the code that this macro is guarding would only represent a small step in that
migration, anyway; and at that point we can start by adding back the code that
this patch is removing.

In the meantime, it's not worth keeping this complexity and the untested/dead
code in the tree.

This addresses the original intent of the bug report which asks for allowing
sndio to be built on more than just OpenBSD. In addition of modifying the
existing --enable-sndio to support this request, the option
--enable-audio-backends was added which takes a list of possible backends to
support per discussion in the bug report.

For example specifying --enable-audio-backends=alsa,jack,pulseaudio,sndio
allows for runtime selection of those four cubeb backends. If all four backends
are available the user can specify `media.cubeb.backend` in `about:config` to
force a specific backend.

Removed superfluous set_define()s as libcubeb's moz.build does the necessary
`DEFINES['...']` assignments for each backend.

In addition logic for finer control of audio backend selection on Android was
added. One can now specify aaudio, opensl or both (which is the default).
