This is similar to a change that landed directly into 74. We don't want to
roll-out to these users yet and we don't want to have to think about it every
release.

Now that GfxInfo supports allowlisting, we can port our existing
configuration in gfxPlatform to using allowlist rules. This will
greatly increase maintainability and certainty that the expected
devices are getting WebRender.

We would like to get to a world where we compare/store enums instead of
strings, and this is a step towards.

Currently the blocklist can block groups of devices, called a
DeviceFamily. However this only allows us to check specific IDs and not
ranges of device IDs like we do currently for the WebRender allowlist.
This patch allows a device family to now specify start and end values
for device IDs we want to match in the blocklist rule.

As part of the WebRender rollout, we have been only allowing users
meeting particular platform, battery and screen size requirements (among
others) to get WebRender by default. This patch adds support for battery
and screen size filters in the blocklist rules to allow us to control
that more easily. It also adds kludgey support for checking for recent
Windows 10 build numbers for allowlist purposes; implementing this the
proper way would require an implementation like driver version checks,
which are much more complicated than most of the rules.

The blocklist currently works by checking the current configuration
against a set of GfxDriverInfo rules. We stop searching as soon as we
find the first match, and return whatever status code that has.
This patch adds a second pass for features marked for allowing. The
current blocklisting rules will still apply as normal. However it will
then review the allowlist rules using the same logic. If we don't get
a match, then we block the feature otherwise we use the allow status
code given in the rule.
New status codes introduced as part of this patch are as follows:
DENIED - Did not match any rules on the allowlist.
ALLOW_ALWAYS - Same as STATUS_OK but passed the allowlist.
ALLOW_QUALIFIED - Same as ALLOW_ALWAYS but should be controlled by
our qualified preference for experimentation purposes.

This patch also exposes the desktop environment and window protocol on
the gfx blocklist, allowing us more control over feature deployment.
This will help with the slow rollout of WebRender to release channels.

This changeset is a simple find and replace of `MOZ_FALLTHROUGH` and `[[fallthrough]]`.
Unfortunately, the MOZ_FALLTHROUGH_ASSERT macro (to assert on case fallthrough in debug builds) is still necessary after switching from [[clang::fallthrough]] to [[fallthrough]] because:
* MOZ_ASSERT(false) followed by [[fallthrough]] triggers a -Wunreachable-code warning in DEBUG builds
* but MOZ_ASSERT(false) without [[fallthrough]] triggers a -Wimplicit-fallthrough warning in NDEBUG builds.

Investigation showed that on this platform the texture unit state becomes
corrupted whenever we set the non-identity swizzling (getting garbage from textureSize()).
Given no easy workaround, we disable swizzling for this GPU family on Mac, for now.

This requires replacing inclusions of it with inclusions of more specific prefs
files.
The exception is that StaticPrefsAll.h, which is equivalent to StaticPrefs.h,
and is used in `Codegen.py` because doing something smarter is tricky and
suitable for a follow-up. As a result, any change to StaticPrefList.yaml will
still trigger recompilation of all the generated DOM bindings files, but that's
still a big improvement over trigger recompilation of every file that uses
static prefs.
Most of the changes in this commit are very boring. The only changes that are
not boring are modules/libpref/*, Codegen.py, and ServoBindings.toml.

Currently it's completely unclear at use sites that the getters for `once`
static prefs return the pref value from startup, rather than the current pref
value. (Bugs have been caused by this.) This commit improves things by changing
the getter name to make it clear that the pref value obtained is from startup.
This required changing things within libpref so it distinguishes between the
"base id" (`foo_bar`) and the "full id" (`foo_bar` or
`foo_bar_DoNotUseDirectly` or `foo_bar_AtStartup` or
`foo_bar_AtStartup_DoNotUseDirectly`; the name used depends on the `mirror` and
`do_not_use_directly` values in the YAML definition.) The "full id" is used in
most places, while the "base id" is used for the `GetPrefName_*` and
`GetPrefDefault_*` functions.
(This is a nice demonstration of the benefits of the YAML file, BTW. Making
this change with the old code would have involved adding an entry to every
single pref in StaticPrefList.h.)
The patch also rejigs the comment at the top of StaticPrefList.yaml, to clarify
some things.
