This patch introduces macros that allow users to detect compiler support for RISC-V intrinsic APIs. These macros, defined in the corresponding intrinsic headers, indicate compiler support independently of the -march setting. Scalar composite macros are derived from their component macros, ensuring they are defined only when all component intrinsic headers are included, improving the accuracy of feature detection.
