Based on dicussion in
[this](https://llvm.discourse.group/t/remove-canonicalizer-for-memref-dim-via-shapedtypeopinterface/3641)
thread the pattern to resolve the `memref.dim` of a value that is a
result of an operation that implements the
`InferShapedTypeOpInterface` is moved to a separate pass instead of
running it as a canonicalization pass. This allows shape resolution to
happen when explicitly required, instead of automatically through a
canonicalization.

Convert subtensor and subtensor_insert operations to use their
rank-reduced versions to drop unit dimensions.

These patterns have been used as a prerequisite step for lowering
to SPIR-V. But they don't involve SPIR-V dialect ops; they are
pure memref/vector op transformations. Given now we have a dedicated
MemRef dialect, moving them to Memref/Transforms/, which is a more
suitable place to host them, to allow used by others.
This commit just moves code around and renames patterns/passes
accordingly. CMakeLists.txt for existing MemRef libraries are
also improved along the way.
