AMDGPU: Rename intrinsics and remove f16/bf16 versions for load transpose (#86313)
Rename the intrinsics to close to the instruction mnemonic names: Use global_load_tr_b64 and global_load_tr_b128 instead of global_load_tr. This patch also removes f16/bf16 versions of builtins/intrinsics. To simplify the design, we should avoid enumerating all possible types in implementing builtins. We can always use bitcast.
