[mlir][spirv] Add control for non-32-bit scalar type emulation
Non-32-bit scalar types require special hardware support that may not
exist on all GPUs. This is reflected in SPIR-V as that non-32-bit scalar
types require special capabilities or extensions.
Previously when there is a non-32-bit type and no native support, we
unconditionally emulate it with 32-bit ones. This isn't good given that
it can have implications over ABI and data layout consistency.
This commit introduces an option to control whether to use 32-bit
types to emulate.
