[llvm] Enable .ptr .global .align attributes for kernel attributes for CUDA (PR #114874)

With the latest changes, this looks good to me. I'm not familiar enough with the semantics of llvm IR to be sure that the default alignment is 1, but that seems like a reasonable and conservative way to go. Please wait for an additional approval before landing.
