[mlir][gpu] Add DecomposeMemrefsPass
Some GPU backends (SPIR-V) lower memrefs to bare pointers, so for dynamically sized/strided memrefs it will fail.
This pass extracts sizes and strides via `memref.extract_strrided_metadata` outside `gpu.launch` body and do index/offset calculation explicitly and then reconstructs memrefs via `memref.reinterpret_cast`.
`memref.reinterpret_cast` then lowered via https://reviews.llvm.org/D155011
