Goal of this patch is to allow disabling all JIT codegen in certain Firefox processes
to let us enable more security mitigations. The JS VM uses the atomic operation stubs
we compile at runtime so this patch converts those to inline assembly instead.
This adds a Python script to generate a header file that has all the inline assembly code.
The inline assembly instructions are based on the JIT-compiled trampoline code.
The generated header is used for all x86/x64/arm32/arm64 builds, so this now includes
no-JIT builds as well.

Except for the following two files, no other header file is still including
"jsapi.h". Add a rule to "check_spidermonkey_style.py" to make sure we don't
regress this progress.
Exceptions:
- "vm/Compartment-inl.h" still needs to include "jsapi.h" for `JS::InformalValueTypeName()`.
- "jsapi-tests/tests.h" still needs to include "jsapi.h" for `JS_ValueToSource()`.

This temporarily adds intl::NumberFormatterSkeleton to the public API so that
we can use it in PluralRules. This allows us to remove the SpiderMonkey
NumberFormatterSkeleton implementation when we convert SpiderMonkey to use
intl::NumberFormat.
We can remove intl::NumberFormatterSkeleton from the public API when we
implement intl::PluralRules in Bug 1704509.

Allow-list all Python code in tree for use with the black linter, and re-format all code in-tree accordingly.
To produce this patch I did all of the following:
1. Make changes to tools/lint/black.yml to remove include: stanza and update list of source extensions.
2. Run ./mach lint --linter black --fix
3. Make some ad-hoc manual updates to python/mozbuild/mozbuild/test/configure/test_configure.py -- it has some hard-coded line numbers that the reformat breaks.
4. Make some ad-hoc manual updates to `testing/marionette/client/setup.py`, `testing/marionette/harness/setup.py`, and `testing/firefox-ui/harness/setup.py`, which have hard-coded regexes that break after the reformat.
5. Add a set of exclusions to black.yml. These will be deleted in a follow-up bug (1672023).

Replace the duplicate lists in mozglue/baseprofiler/public and js/public with
a shared list. Add this list to both moz.build files so it is published twice
which simplifies supporting different standalone configurations.

For now this generates just CACHE_IR_OPS and CACHE_IR_SHARED_OPS in CacheIROpsGenerated.h
but the plan is to use this to generate parts of the IR writer and compiler/transpiler
interface. The spewer could also potentially be improved now that each operand has a name
and more precise type.
Generating the IR writer will likely happen incrementally so that will give us
another chance to double check the precise types match what's in the YAML file.

Because most of the recent changes to irregexp were patches I contributed myself, we barely need to change any of the shim code.
The only notable change is the addition of '#define COMPILING_IRREGEXP_FOR_EXTERNAL_EMBEDDER'. This is the solution that Jakob Gruber and I eventually came up with for the question of what to do with awkward V8 code that SM doesn't want. For example, NativeRegExpMacroAssembler::Match (in regexp-macro-assembler.cc) gets down in the muck with the internal details of V8's String implementation. It would be most convenient for SM if that function just didn't exist; we aren't going to use it, and we don't want to have to define a bunch of unused string API gunk in our shim. The answer is to wrap functions we don't need in "#ifndef COMPILING_IRREGEXP_FOR_EXTERNAL_EMBEDDER", which solves our problem and is minimally disruptive upstream.

"disjunction" and "unit" types aren't yet supported, because ICU doesn't

- Add NumberFormatterSkeleton as a helper class to construct a number formatter
skeleton. When the "Intl.NumberFormat Unified API" proposal gets implemented
a more feature-rich class may be necessary.
- In addition to a UNumberFormatter instance, NumberFormatObject now also
stores a UFormattedNumber instance. This avoids a performance regression
compared to creating a new UFormattedNumber object each time a number gets
formatted. (In micro-benchmarks 20% regressions were seen, with a cached
UFormattedNumber the same micro-benchmarks even improved by ~33%.)
- Add accessors for reserved slot values to NumberFormatObject to improve
readibility.

There is a big difference between generated source files that are built
directly, and those that are only included.
In the latter case, the build system won't know the files that does the
including depends on the generated source. So those sources do need to
be built during the export tier.
But in the former case, the build system has all the dependency
information it needs, and, while these generated sources are currently
built as part of the export tier, they don't actually need to be. We're
going to change that, and in preparation, we rename included files so as
to be more clearly identified.
