This adds support for Software Tag-Based KASAN (KASAN_SW_TAGS) when CONFIG_RUST is enabled. This requires that rustc includes support for the kernel-hwaddress sanitizer, which is available since 1.96.0 [1]. Unlike with clang, we need to pass -Zsanitizer-recover in addition to -Zsanitizer because the option is not implied automatically. The kasan makefile uses different names for the flags depending on whether CC is clang or gcc, but as we require that CC is clang when using KASAN, we do not need to try to handle mixed gcc/llvm builds when Rust is enabled.
