Remove done and release distinction. Chrome is not using either as
it tracks texture access using other synchronization mechanisms
(semaphores, flush finish procs). Now there is just fulfill and release
where release is called when the texture can be deleted. Also,
release proc can be null.
Simplify texture idle mechanism as the "flushed" state was only used to
implement the old idea of a release proc. The "finished" idle state is
still used to implement the new release proc. Though, it could also be
removed if GrTexture were to be removed for textures returned by fulfill.
Not directly tied to this bug, but a new YUVA factory will be required
and it's good to clean things up first to avoid adding another
instance of the current complexity.

a G3 dependency with no SkUserConfig.h relies on the legacy API.
Once this lands, we will migrate them and others, then remove the
staging API. The inverted staging flag is kind of nice, actually - I may
use that pattern in the future. It means less total CLs and it's just as
easy to flip the bit on or off during debugging.

Consolidates validity checks of the SkYUVAInfo with the color types

assist with configuring planes to share a common allocation.
SkYUVAPixmaps is a collection of SkPixmaps that are valid for a

own the memory. It consolidates validity checking of SkPixmaps with
the SkYUVAInfo. Replaces sk_gpu_test::YUVAPixmaps.
Minor tweaks to SkYUVAInfo naming, parameter order consistency, adds a

The check is only applied if it is safe to replace the copy by a const

it is only used as a const, i.e. only const methods or operators are

`const` on a non-pointer/reference return type typically doesn't add
value and can have negative side effects. (i.e., returning a
`const std::string` isn't meaningfully different from returning a
`std::string`, but can sometimes inhibit move-related optimizations.)
In Skia's case, the priv() functions are a notable exception where const
return types are intentional and valuable. These calls have been marked
with NOLINT to exclude them from the check.
This check does not affect pointer and reference returns, where
constness is important.

SkMipMap::Build fails surprisingly often. Fall back to unmipped promise images in that case.
The prior approach created the mipMaps too late (i.e., at backendTexture creation time) for the test harness to change its mind about the mip status of a promise image. This approach moves the mipmap creation earlier - to when the PromiseImageInfos are created (i.e., at SKP deflation time).

When timing DDL performance with SKPs, if the mipmapping requirements of a given SkImage are gotten wrong at record time, the mipmaps will keep getting regenerated over and over again. This CL works around the problem by just creating all promise images as mipmapped. A better (but longer term solution) would be to examine the actual draw ops w/in an SKP.
Even more aggressively, we may want to disable mipmap regeneration w/in DDLs.
For desk_nytimes.skp on Windows/gl we have:
before CL after CL
w/ DDLs 7.999 3.136
w/o DDLs 1.953 1.863
This perf improvement won't be seen by Chrome since, presumably, they're creating their backend textures w/ the correct mipmappedness. Additionally, they, hopefully, aren't recording the same DDL over and over again (with incorrect mipmappedness).
