Instead of snprintf.
Because some standalone code uses those functions directly or indirectly,
and PrintfTarget lives in mozglue, they now need to depend on mozglue
instead of mfbt. Except logalloc/replay, which cherry-picks what it
uses, and the updater, for which we keep using vsnprintf.

This code is important for transitioning between the skeleton UI code and the
full-featured browser window code. Additionally, the original logic of disabling
when not on the default theme no longer applies, because it was intended to
eliminate white flashes in dark mode. However, with the skeleton UI, those
white flashes no longer occur.

If we error out in, say, DrawSkeletonUI, the window we created will be orphaned
and left to sit there indefinitely. This patch fixes that by separating the
error from the consume result.

We know that some GV installations (particularly but not exlcusively Focus) are
failing to load `libxul.so` during early Gecko bootstrapping. Unfortunately
a boolean pass/fail result is not giving us sufficient information to be able to
properly troubleshoot this problem.
This patch adds `mozilla::Result`-based return values to `XPCOMGlueLoad` and
`GetBootstrap` in an effort to produce more actionable information about these
failures.
We include either a `nsresult` or, if the failure is rooted in a dynamic linker
failure, appropriate platform-specific error information:
* On Unix-based platforms, a `UniqueFreePtr<char>` containing the string from `dlerror(3)`;
* On Windows, the Win32 `DWORD` error code from `GetLastError()`.
For non-Android platforms, I updated them to handle the new return type, but
otherwise did not make any further changes.
For Android, we include the error information in the message string that we pass
into the Java `Exception` that is subsequently thrown.

No code changes.
Build issues were found by renaming `MOZ_GECKO_PROFILER` to something else in toolkit/moz.configure, in both unified and non-unified builds, on all supported platforms.
Also updated some profiler-related comments.

New headers BaseProfilerLabels.h and ProfilerLabels.h now contain all label-related APIs.
These files were hg-copied from the main headers, to preserve history, and then non-label content was removed from the main headers.
The "RAII" macros were moved to these *ProfilerLabels.h headers, because that's the most-common header in which they're needed. Meta-bug 1681416 will probably move these again as needed.

{Base,}ProfilerMarkers.h can now rely on {Base,}ProfilerState.h (and just one function forward declaration), so they don't need to include {Base,Gecko}Profiler.h anymore.
Thanks to that, {Base,Gecko}Profiler.h can now include {Base,}ProfilerMarkers.h at the top.
Also, BaseProfilingStack.h should not include BaseProfiler.h (include loop, can cause failures) not algorithm (not used).

New headers BaseProfilerState.h and ProfilerState.h now contain most state-reading APIs.
These files were hg-copied from the main headers, to preserve history, and then chosen declarations were kept only in the relevant header.
This is needed in a following patch, where new headers *ProfilerLabels.h use `profiler_is_active()`.

ProfileBufferCollector::SamplePositionInBuffer() and BufferRangeStart() need to provide indices in the same main buffer, because they will be used to discard old data (at some previous `SamplePositionInBuffer`) once the `BufferRangeStart` indicates that it is not referenced by the profiler anymore.
Because the periodic sampler uses a local buffer (to avoid allocations and locks), we need to record the special location from the main profiler buffer in ProfileBufferCollector.

This avoids paying a cost for animating the skeleton UI for faster startups.
Slow startups don't seem to be affected, given the data available. This is
likely due to slow startups being dominated by IO.

This makes mozilla::PrintfTarget consistent across all locales (not
printing e.g. "," instead of "." for the decimal point in floats in some
locales)
This implementation passes all the glibc tests in stdio-common/tfformat.c
except two tests because of the difference in how values like e.g 0.25 are
rounded. Printf in glibc and on MacOS, as well as Rust std::fmt, round to
nearest, ties to even. Double-conversion, as well as printf on Windows
and conversion functions in ECMAScript round to nearest, ties away from
zero.
The standard for printf says rounding is implementation-defined so
either way is technically correct.
Differential Revision: https://phabricator.services.mozilla.com/D102699
While at this point PrintfTarget doesn't use double-conversion, add a
test that it can (and thus will) handle the largest double output possible
with the default %f precision.

It is worth noting that some of these tests fail on Windows for rounding
difference reasons (see later commit from this bug for more details),
and on both Windows and mac for differences in formatting for INFINITY
and NAN. All the tests pass on Linux (since the underlying printf is
currently glibc's).

The standard for printf says that for integers, the result of converting
zero with an explicit precision of zero shall be no characters. But
flags and width still need to apply.

%F and %G are the same as %f and %g, but using caps for the exponent
indicator, and for "inf"/"nan" for infinity and NaN.
%n$E is the same as %E, but taking the nth argument.
