"Please note since the last release the subproject tarballs have been
removed"

Used upstream tarball llvm-project-22.1.0.src.tar.xz for all packages
and linked subproject hash files to ../llvm-project.hash.
Removed patches which fix build errors caused by subproject tarballs.
Removed handling of third-party-21.1.8.src.tar.xz which is included in
the monolithic tarball.
Added _SUBDIR variable or updated _INSTALL_CMDS when needed.
For compiler-rt:
Removed both patches, they are not needed anymore.
Added patch to fix aarch64 build.
Added dependency on gcc >= 15.x because libcxx now depends on gcc >=
15.x: https://github.com/llvm/llvm-project/pull/165684
warning "Libc++ only supports GCC 15 and later"
Building with gcc 14.x causes many build errors like
