Do more math on the CPU to avoid per-fragment ALU operations.
Use a mat3x2 instead of mat2x3 to avoid padding.

Replace the ShouldRun() method with Apply() which will do the
transformation if it needs to be done, otherwise returns
'SkipTransform'.
This reduces a bunch of duplicated scanning between the old ShouldRun()
and Transform().
This change also adjusts code style to make the transforms more
consistent.

To match the spec.
Also add a bunch of missing texture test cases to
src/tint/ast/builtin_texture_helper_test.cc. Fix all the tests that were
broken because these were not being exercised.
