James Price 6176c85be8 tint: Preserve padding in matrices with three rows
The PreservePadding transform now decomposes writes to matrices with
three rows into separate column vector writes, to avoid modifying
padding between columns.

James Price 8753796aac tint: Add PreservePadding transform
This is used to ensure that assignments to host-visible memory do not
modify padding bytes in structures and arrays. We decompose
assignments of whole structure and array types into member-wise or
element-wise copies, using helper functions.

This is used in all backends except HLSL, which already decomposes
memory accesses.
