  [SPIRV] Add support for selection of G_MEMCPY_INLINE (#201925)

`G_MEMCPY_INLINE` is the same as `G_MEMCPY` but it's supposed to
guarantee the instruction will not be lowered to an external function
call. This is useful for projects like `libc`.

In SPIR-V, we would never lower to an external function call, we always
lower `G_MEMCPY` to `OpCopyMemory` or `OpCopyMemorySized`, or the copy
is optimized out, so we should be able to handle `G_MEMCPY_INLINE` and
`G_MEMCPY` the same.
