[libclc] Remove (vload|vstore)_half helpers (#137181)
These were only being used when compiling with versions of clang older than clang 6. As such they were essentially unsupported and untested. This somewhat simplifies the codebase, producing fewer helper functions in the final builtins library. It also avoids typed pointer IR. There's no change to any of the targets' bytecode other than removing these helper functions.
