LOG: [clang] Replace PointerUnion::dyn_cast with llvm::dyn_cast_if_present (NFC) (#233191)

PointerUnion::dyn_cast has been soft-deprecated in favor of
llvm::dyn_cast and llvm::dyn_cast_if_present.  This patch replaces the
former with llvm::dyn_cast_if_present in
FriendTemplateDecl::getFriendDecl.

This is the only place under clang/ where migrating to llvm::dyn_cast
would trigger an assertion failure during check-clang.
