[libclc] Move shuffle/shuffle2 to the CLC library (llvm#135000)
This commit moves the shuffle and shuffle2 builtins to the CLC library. In so doing it makes the headers simpler and re-usable for other builtin layers to hook into the CLC functions, if they wish. An additional gentype utility has been made available, which provides a consistent vector-size-or-1 macro for use. The existing __CLC_VECSIZE is defined but empty which is useful in certain applications, such as in concatenation with a type to make a correctly sized scalar or vector type. However, this isn't usable in the same preprocessor lines when wanting to check for specific vector sizes, as e.g., '__CLC_VECSIZE == 2' resolves to '== 2' which is invalid. In local testing this is also useful for the geometric builtins which are only available for scalar types and vector types of 2, 3, or 4 elements. No codegen changes are observed, except the internal shuffle/shuffle2 utility functions are no longer made publicly available.
