730bf8c8 - [Clang] Update target parser for address spaces for AMDGPU (#175998)

[Clang] Update target parser for address spaces for AMDGPU (#175998) Summary: This does three things: 1. Allows address_space<0>, this is not a no-op currently as it has real type checking signficange. The SPIR-V backend also does not currently use `0` as a generic address space. 2. Allows parsing address space pointers inside vectors, this required parsing the correct closing bracket instead of the first found 3. Adds the two missing AMDGPU builtin types.
