  [mlir][Memref] Introduce a memref::ExtractAlignedPointerAsIndexOp

As experience with memref::ExtractStridedMetadataOp grows we are
still missing a simple way to extract the pointer held by a memref
and lower to different backednds (LLVM, SPIRV, library calls).

This revision introduces a memref.extract_aligned_pointer_as_index that
returns an index containing the aligned pointer of the strided memref.

This operation is intended to be used solely as step during lowering,
it has no side effects. A reverse operation that creates a memref from
an index interpreted as a pointer is explicitly discouraged.
