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. Add a set of exclusions to black.yml. These will be deleted in a follow-up bug (1672023).

I see atom dropping code generated in release builds for stuff like dropping the
"class" atom here:
https://searchfox.org/mozilla-central/rev/4df8821c1b824db5f40f381f48432f219d99ae36/servo/components/style/gecko/wrapper.rs#592
That is silly, and I hope making Atom be able to be used in const context will
help the compiler see that yeah, we're not doing anything interesting and the
atom shouldn't get dropped.
It also allows us to get rid of a few lazy_static!s, so we should do it anyway.
In order to accomplish this, compute the offset into gGkAtoms manually instead
of going through the static_atoms() array and then back to the byte offset.

This is more consistent with what the Rust bits of the style system do, and
removes a pointer from ComputedStyle which is always nice.
This also aligns the Rust bits with the C++ bits re. not treating xul pseudos as
anonymous boxes. See the comment in nsTreeStyleCache.cpp regarding those.
Can't wait for XUL trees to die.

And thus massively speed up ascii-case-insensitive atom comparisons when both
atoms are lowercase (which is the common case by far).
This removes almost all the slow selector-matching in this page, and it seems
an easier fix than storing the lowercased version of all class-names in quirks
mode in elements and selectors...

Specifically:
- nsICSSAnonBoxPseudo --> nsCSSAnonBoxPseudoStaticAtom
- nsICSSPseudoElement --> nsCSSPseudoElementStaticAtom
The `nsI` prefix isn't necessary because these are no longer XPIDL types, and
the `StaticAtom` suffix makes their meaning clearer.

This saves one word per static atom, per process.
The `nsGkAtoms` change is only a small part of this commit.
In regen_atoms.py:
- There is now only one link name per platform: nsGkAtoms::sAtoms[].
- But there is a new constant per atom, giving the index into
nsGkAtoms::sAtoms[].
- And the `atom!` macro for each atom indexes into nsGkAtoms::sAtoms[] using
the index constant.
- A couple of `*mut` pointers are now `*const`.
Elsewhere, the `(nsStaticAtom*)` casts within the `AppendElement()` calls are
necessary to avoid link errors, presumably due to some template instantiation
wrinkle.

Specifically, give all the string templates the ''' form, and give them all
`_TEMPLATE` suffixes. This requires slightly changing the newline handling.

For example, in dom/base/nsGkAtomList.h, we currently have:
GK_ATOM(mouseWheel, "mouseWheel") // For discrete wheel events (e.g. not OSX magic mouse)
but if we change to
GK_ATOM(mouseWheel,
"mouseWheel") // For discrete wheel events (e.g. not OSX magic mouse)
The parser didn't handle the declaration
It's a sub-class of nsAtom, useful for cases where you know you are dealing
exclusively with static atoms. The nice thing about it is that you can use
raw nsStaticAtom pointers instead of RefPtr<>. (In fact, the AddRef/Release
implementations ensure that we'll crash if we use RefPtr<nsStaticAtom>.)
