  [CIR][AMDGPU] Adds `__amdgpu_buffer_rsrc_t` in the buffer-resource address space (#204782)

CIR previously lowering every AMDGPU opaque pointer to
`!cir.ptr<!void>`. Now `__amdgpu_buffer_rsrc_t` lower to
`!cir.ptr<!void, target_address_space(8)>` similar to (`ptr
addrspace(8)` in LLVM IR) matching CodeGen.

This change requires for upcoming raw buffer load/store/atomic builtins.
Those builtins `__builtin_amdgcn_raw_buffer_load/store_b*,
__builtin_amdgcn_raw_ptr_buffer_atomic_*` take a
`__amdgpu_buffer_rsrc_t` as operand, and the corresponding LLVM
intrinsics expect a `ptr addrspace(8)` resource argument.
