  -----------
  [DTLTO][Clang][LLD] Fix DTLTO for multi-call LLVM driver toolchain (#162456)

Add DTLTO linker option `--thinlto-remote-compiler-prepend-arg` to
enable support for the multi-call LLVM driver that requires an
additional option to specify the subcommand, e.g. "llvm clang ...".

Fixes https://github.com/llvm/llvm-project/issues/159125.
