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

And remove the WrapArraysInStructs transform.
Wrapping arrays in structures becomes troublesome for `const` arrays, as
currently WGSL does not allow `const` structures.
MSL 2.0+ has a builtin array<> helper, but we're targetting MSL 1.2, so
we have to emit our own. Fortunately, it can be done with a few lines of
templated code.
This produces significantly cleaner output.

Changes Dawn and Tint to use a 3x3 matrix for external texture
YUV-to-RGB conversions. This will allow us to use standard matrices
as they exist in SkYuvMath.

With this change, the backend sanitizers always run the
MultiplanarExternalTexture transform. If the new option is enabled, it
auto-generates bindings for this transform.
This change also enables this auto-generation for the Tint commandline
application, as well as for the fuzzers.
