The conceptual meat of this change is that instead of taking a local-to-
device scale factor and the local stroke width, CalcNumRadialSegments
now takes the approximated device-space stroke radius. The main benefit
of this is that hairlines can be defined exactly without needing to
invert the local-to-device matrix or otherwise estimate a local-space
radius that would transform to the 1px hairline. The actual math for
regular strokes remains the same (scale factor * radius), but is moved.
In addition, this CL fixes a bug I had introduced in
https://skia-review.googlesource.com/c/skia/+/502059/
where I had not realized the CPU code operated on stroke *width* and the
GPU code operated on stroke *radius*, so updating them to use the same
equations w/o changing their inputs actually caused us to overestimate
the number of radial segments required. With this change, both the CPU
code and GPU code operate on stroke radius.
Between that bug fix and simplifying the hairline stroke radius math,
I am expecting lots of slight AA changes around stroked paths.
Lastly, I entirely removed the StrokeTolerancesBuffer, which was a class
that buffered up calculations of CalcNumRadialSegments by looking at the
entire list of paths in an op and putting them into a 4-lane SIMD
function instead. This isn't currently available for Graphite and makes
it harder to consolidate the radial segment calculations. Locally I
found no noticeable difference in the patch writing microbenchmarks
(where it would be more significant), and somehow the motionmark SKPs
were actually a touch faster. I'm hopeful that we can drop this
complexity and not take a large performance hit.

For usages of constants in classes outside of skgpu::tess (e.g. when
using tessellation in skgpu::v1 or skgpu::graphite), the constants are
accessed with tess::. This is just to help with clarity since it scopes
the constant name. However, functions and types are still referred to
without that, and using namespace skgpu::tess is used to keep those
references simpler.
In headers, tess:: is added when there are only a few usages of the
types, or it's brought in as an alias.

This should make it so the HW tessellation path renderers are never
used; it will always select the atlas or direct fixed-count renderers
instead. This CL will give us a good indication of what visual diffs
to expect, layout tests to rebase, and any performance regressions.
If those are acceptable, then we can proceed with the rest of the code

FixedCountBufferUtils.h.
The tessellator hierarchy has been moved into src/gpu/ops and all the
v1 guards are removed since they were already solely v1 after the static
functions were lifted out. The hierarchy and subclasses are preserved
but have been combined into just StrokeTessellator.h and
PathTessellator.h instead of separate files for the subclasses.
All the rest of the little changes are updating references and includes.

Rather than having this class write directly to a GPU buffer, which
also included an ugly hack to support extra instance data that was not

We are making src/gpu/tessellate independent of v1, and more represent
math and types that just know how to tessellate, so this seems like the
right place again for this file.

This is just a bunch of renaming, and for now the tessellate/shaders
directory remains untouched. The next steps will be to clean up and
remove all Ganesh v1 dependencies from tessellation.

This allows us to batch multiple paths together in a single
tessellation. The first user will be the atlas, but the convex
renderer is also a good candidate.

The pathMatrix is applied on the CPU while the geometry is being
written out. It is a tool for batching, and is applied in addition to
the shader's on-GPU matrix. This CL also updates GrPathStencilCoverOp
do do all its path transformations with pathMatrix on the CPU side.
The next step will be for atlases to use the pathMatrix instead of
creating uber paths.

GrVertexWriter is itself a pointer, so this is a double reference.
It's ~20% faster on the micro benchmark to store this as a literal
GrVertexWriter. The motivation for this CL is that we need to optimize
the CPU-side processing for tessellation in order to place the
tessellation atlas above the cached triangulating path renderer in the
chain.

When isinf is not supported, we simply add another instanced attrib that
tells the shader exactly what type of curve it's dealing with.

The Tessellator classes will survive in the NGA and they use
GrMeshDrawOp::Target - but GrMeshDrawOp will not survive.
This is a prelude to making all the remaining GrOp-derived classes OGA-only.
