Like https://chromium-review.googlesource.com/c/chromium/src/+/1005362,
this patch adds a way for Chrome and Skia to share a set of driver
workaround names so that they can be turned on by Chrome (or Skia) as
needed.
To avoid weird cross-repository dependencies, the generator script is
duplicated in Skia.
This patch just adds a few dummy workaround names to make sure the build
process is working. The followup to this is to add workaround init
to GrContext/GrContextOptions and to start implementing individual
workarounds.
Implementing these workarounds is to support Chrome's "out of process
raster" which will use Ganesh without a command buffer, and so will not
have the workarounds that the command buffer provides.

The big api level change here is that the getBackendInfo calls now return by value
instead of a pointer. These changes are being made in support of Vulkan so that
the client can update the VkImageLayout on the GrBackendTexture and have that
update get reflected in our internal tracking of the image. This is done by storing
a ref counted GrVkImageLayout object on the GrBackendTexture and the GrVkImage.

Interpolates the acual curve's local coverage values from the corner
box vertices, rather than an approximation based on the tangent.
Clamps curve segment total coverage values above 0. This prevents us
from using negative coverage (which is obviously wrong) when the curve
approximation function is slightly inaccurate. Moves
GrCCTriangleShader.h into GrCCCoverageProcessor.cpp.

Ever since we added drawShadow to the public api, blurs have necessarily
part of the core. This CL just formalizes that.
This should also allow us to have builds that exclude all of /effects (for code size)
and still be valid.
Will follow-up with a change to deprecate SkBlurMaskFilter and SkBlurQuality (both no longer needed).

Modifies triangle corner shaders to just approximate their coverage with
linear values that ramp to zero at bloat vertices outside the triangle.
For the vertex backend, since corners now have the same fragment shader
as the rest of the triangle, we fold them in with the other steps and
draw triangles in a single pass.
The geometry backend still draws triangles in two passes, as there is
not an apparent performance advantage in combining them.
Updates SampleCCPRGeometry to better visualize this new geometry by
clearing to black and drawing with SkBlendMode::kPlus.

Reland all the things
This CL splits the old GrAtlasGlyphCache into a GrAtlasGlyphCache and an GrAtlasManager.
The GrAtlasManager itself is split into a rather limited base class (GrRestrictedAtlasManager)
and the all powerful GrAtlasManager. The GrRestrictedAtlasManager is available at op creation
time and provides access to the proxies backing the atlases. The full GrAtlasManager is
only available at flush time and allows instantiation of the proxies and uploading to them.
In the DDL world all of the DDL Contexts will receive a GrRestrictedAtlasManager-version of the
GrAtlasManager in the main thread. This future atlas manager will have had all of its
GrDrawOpAtlases created (but not instantiated) so there should be no race conditions.

It doesn't make sense to multiply by coverage when drawing to stencil.
This could theoretically work with FPs that discard and/or modify
the sample mask, but for the time being an analytic FP means one that
calculates a coverage value.
