Add runtime compatibility patch set

Add an LLVM 22.1.6 runtimes patch for building libc++, libc++abi, and llvm-libgcc together. The patch lets libc++abi accept llvm-libgcc as the provider of the LLVM unwinder, keeps the libgcc_s version script private to libunwind so it does not leak into libc++abi links, and adds an opt-out for building compiler-rt inside llvm-libgcc when an exported external builtins archive is available. Add libxcrypt patches for current Clang/glibc builds: avoid treating Clang as old GCC in yescrypt assembly selection and adjust yescrypt strchr call sites for the newer glibc const-correct prototype behavior. Add a mandoc 1.14.6 patch for zstd-compressed manual pages, including configure checks, linker flags, documentation, section matching, and decompression handling. Remove the obsolete Perl 5.42.2 LBI patch from the patch set.
