Lei Zhang 89b595e141 [mlir][spirv] Detach memory space mapping from type conversion ... This commit moves MemRef memory space to SPIR-V storage class conversion out of the main SPIR-V type converter. Now the mapping should happen as a prelimiary step before performing the final conversion to SPIR-V. Flows are expect to write their own memory space mappings like the `MapMemRefStorageClassPass` to handle memory space mappings according to their needs. This is needed because SPIR-V is serving multiple client APIs, including Vulkan and OpenCL. Different client APIs might want to use different storage classes for buffers in a particular memory space, e.g., `StorageBuffer` for Vulkan vs. `CrossWorkgroup` for OpenCL when converting the default 0 memory space. Hardcoding a specific mapping makes that hard. While it's possible to embed selection logic further inside the main type converter, it will make the main type converter even complicated. So it's better to separate the concerns, as mapping the memory space is really concretizing the meaning of those numeric memory spaces in the particular context of SPIR-V lowering.
