This CL make transform AddBlockAttribute always try to wrap types used
by buffer variables into a struct, in order to generate valid GLSL code
for assigning one buffer struct variable to another buffer struct
variable.

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.

This transform breaks up matNx2<f32> matrices used in uniform buffers
into column vectors, which fixes std140 layout rules.
Used by the SPIR-V and GLSL backends.
Re-enable tests that were disabled for these cases.
