Add compatibility with LLVM 22.x.

LLVM 22 removes the IntrusiveRefCntPtr<vfs::FileSystem> parameter from
the PGOOptions constructor. The VFS was moved to PassBuilder directly
(see llvm/llvm-project#160188), allowing all passes that need filesystem
access to get it from PassBuilder rather than routing it through
PGOOptions.

Add LLVM_VERSION_MAJOR version guards to retain the FS argument for
LLVM 17-21 while dropping it for LLVM 22+.
