Ben Clayton 84b43d61fa tint/writer: Handle unnested, uniform matCx2 matrices
Shuffle the transform orders to ensure that these are embedded in a structure before running the Std140 transform.

Add more end-to-end tests for these.

As pointed out in tint:1673, arrays of matrices are not correctly decomposed by the Std140 transform.
This will be addressed by a later change.

Bug: tint:1673
