In preparation of patches that will allow V4L2 decoding to work by
default on Linux.
The VA-API and V4L2 backends provide essenitaly the same output -
DMABufs in formats like NV12/P010 etc. - and face similar restrictions
e.g. GL driver features. It therefore makes sense to have the same media
switches and in fact some of them - most importantly
`VaapiVideoDecodeLinux` - already apply to V4L2.
Thus in order to reduce confusion and avoid code duplication, rename
some of the `Vaapi` swiches used in common code to `Accelerated` but
keep the `Linux` suffix, making it clearer to what they apply. Also
ensure they are used for both APIs the same way and update the
`vaapi.md`.
Finally, add `AcceleratedVideoDecodeLinuxZeroCopyGL` to the VA-API
documentation.

Add a AllowSwiftShaderFallback finch feature as a killswitch. This
is currently *enabled by default* with a deprecation message.
Once AllowSwiftShaderFallback is disabled:
Disable falling back to SwiftShader as a result of multiple GPU crashes.
Instead, fall back to the display compositor.
Disable falling back to SwiftShader as a GL implementation unless it's
the only available implementation (current behaviour) AND
--allow-unsafe-swiftshader is passed to Chrome. This allows testing of
Chrome on systems without GPUs without exposing end users to
security issues in the SwANGLE stack.
Continue to allow SwiftShader to be used if it's explicitly requested
by command line with the --use-angle=swiftshader flag. This allows testing of Chrome's rasterization and WebGL using SwiftShader.

Refactors the unexpected pass finder disable annotation code so it is
no longer tied to expectation removal and uses the refactored code to
add a disable-narrowing annotation. This is similar to the existing
disable annotations, but prevents expectations from having their scope
automatically narrowed.
Also un-narrows several expectations that are intentionally broad and
prompted the addition of this functionality.

Currently, Chrome uses legacy SwiftShader GL as the WebGL fallback when
a hardware GPU isn't usable for the purpuse of rendering WebGL content.
As we're in the process of changing legacy SwiftShader GL to SwANGLE,
this CL adds a new flag which allows using SwANGLE for WebGL only.
To clarify, current switches with legacy SwiftShader GL:
Software GL: --use-gl=swiftshader
Software WebGL only: --use-gl=swiftshader-webgl
With SwANGLE, the new switches will be:
Software GL: --use-gl=angle --use-angle=swiftshader
Software WebGL only: --use-gl=angle --use-angle=swiftshader-webgl
