  [MLIR][AMDGPU] Redirect transfer read to masked load lowering (#146705)

This PR reworks https://github.com/llvm/llvm-project/pull/131803.
Instead of applying the optimization on transfer_read op, which is too
high level, it redirect the pre-existing pattern onto maskedload op.
This simplified the implementation of the lowering pattern. This also
allows moving the usage of the pass to a target dependent pipeline.
