We add a configuration option for SIMD and apply ENABLE_WASM_SIMD
throughout the engine as appropriate, mostly to insert #error or
MOZ_CRASH where things need to be done in later patches or for
architectures that we won't currently consider.
We add a command line switch for the shell and an option for
about:config and plumb the value of this through the engine.

We haven't shipped direct manipulation yet so we don't need these and they still cause blank windows for a very small number of users.

There are many limitations currently, but this prototype should successfully
render most basic AVIF images. Known limitations:
- No support for any derived image items (crop, rotate, etc.)
- No support for alpha planes
- No support for ICC profiles (bug 1634741)
- The primary image item must be an av01 (no grid support)
- HDR images aren't tone-mapped

Adds IpdlQueue capability to PWebGL actors. The WebGLChild, used in content processes, implements SyncProducerActor and AsyncConsumerActor because it sends (sync and async) messages and receives responses to them that it reads as async messages. The WebGLParent, used in the compositor process, is a SyncConsumerActor and AsyncProducerActor for dual reasons.

I'm not positive that the intended behavior of PreferencesWriter::Flush
is to ensure that any pending writes to the preferences file are
completed, but that seems like what it ought to be for, and it does
not look water-tight. For one, adding a sync runnable to a thread pool
will not ensure that any previously submitted runnables have completed
by the time it returns. And two, the exchange on sPendingWriteData only
guarantees that the write has started.
This change simply ensures that the write to disk has been completed
before returning.

This requires adding a new JSOptions field (for internal use within the shell),
as well as a new browser pref (to support possible Cranelift benchmarking on
aarch64).

This adds a splits the non-incremental threshold parameter into one for small heaps and one for large. What counts as large and small are controlled by the existing parameters that were previously used for dynamic heap growth. I also renamed the parameter from "non-incremental threshold" to "incremental limit".
The small heap parameter is increased to 1.4. This avoids non-incremental GC on facebook and reddit as reported in the dependent bugs and allows us to remove the splay latency hack that was previously necessary.

We distinguish between two kinds of pref syntax.
- "Default pref files" are the ones that come with Firefox, constructed from
`all.js` and similar files.
- "User pref files" are the ones that get created in the user's profile.
`prefs.js` is the one that Firefox creates and overwrites every time a pref
changes. `user.js` is the one that users can create themselves.
We also have two basic kinds of pref.
- Default: `pref(...)` and the unfortunate `sticky_pref(...)`.
- User: `user_pref(...)`, which override but don't replace the default.
It only makes sense for user pref files to contain user prefs; users shouldn't
be able to create default prefs or change default pref values.
But it turns out that user pref files have been able to define default prefs
pretty much forever. This appears to be an oversight, and this commit restricts
things so that user pref files cannot contain default prefs.
The commit also fixes an incorrect comment in testParser.js.

In this changeset, we add a preference that will simply disable F12 when it is set.
UI and tests are in followup patches
