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.
