This adds aliases like skvx::float2, float4, etc. to SkVx.h and goes
through existing usages of SkVx to standardize on those aliases, or
refer to the full name directly.
In particular, this lets us clean up the equivalent aliases in
src/gpu/tessellate, src/gpu/graphite/VectorTypes and src/gpu/ganesh/GrVx
Where possible, I switched to using skvx::Foo directly and leveraged
auto to make it less redundant. Headers always used the full type
except for PatchWriter.h and Rect.h because of the number of their
usages. In this case, the alias is scoped to private so it can't leak.
This is prep to migrate older code that is still using SkNx and its
aliases like Sk4f to SkVx as well.
