We still use the StrideAttribute AST node in the SPIR-V reader for
strided arrays and matrices, which are then removed by transforms.
The WGSL parser no longer has to handle attributes on types.

Since this was the only attribute allowed on structures, we can also
remove the parsing code for them. However, we still need to have
attributes on the struct AST node, since the AddSpirvBlockAttribute
transform adds one.

This transform ensures that expressions are evaluated in the order
defined in the WGSL spec. It does this by making sure to hoist
expressions that have side-effects (calls) along with variables that may
receive these side-effects to lets in the correct order.

UniqueAllocator is used to allocate unique instances of the template type.
This will be used to clean up duplicated code we have throughout Tint.

The multiplanar external texture transform has been integrated into
Dawn, which means we have no use for the single plane transform - so it
should be deleted.
