This patch adds support for masked vector.gather ops using the
vector.mask representation. It includes the implementation of the
MaskableOpInterface, Linalg vectorizer support and lowering to LLVM.

The rewrite driver is typically applied to a single region or all regions of the same op. There is no longer an overload to apply the rewrite driver to a list of regions.
This simplifies the rewrite driver implementation because the scope is now a single region as opposed to a list of regions.
Note: This change is not NFC because `config.maxIterations` and `config.maxNumRewrites` is now counted for each region separately. Furthermore, worklist filtering (`scope`) is now applied to each region separately.

This patch introduces the initial bits to support vector masking
using the `vector.mask` operation. Vectorization changes should be
NFC for non-masked cases. We can't test masked cases directly until
we extend the Transform dialect to support masking.

- argument name 'isLastOutput' in comment does not match parameter name
'hasOutput'.
- override is redundant since the function is already declared 'final'.
This patch introduces the lowering for xfer ops masked with `vector.mask`.
Vector reductions are not lowered yet because new LLVM intrinsics are needed
in the LLVM dialect.
