This PR adds conversion patterns for MemRef to the `convert-to-spirv` pass, introduced in #95942. Conversions from MemRef memory space to SPIR-V storage class were also included, and would run before the final dialect conversion phase. **Future Plans** - Add tests for ops other than `memref.load` and `memref.store` --------- Co-authored-by: Jakub Kuderski <kubakuderski@gmail.com>
