  [clang] Fix -Wunused-template in frontend helpers (NFC) (#202980)

Two frontend templates trip `-Wunused-template`.

In `ASTUnit.cpp`, `moveOnNoError` is an unused duplicate (the live copy
lives in `PrecompiledPreamble.cpp`), so it's removed.

In `CompilerInvocation.cpp`, `mergeMaskValue` and `extractMaskValue` are
the option-marshalling helpers that `OptParser.td` names for bitfield
options. No option currently uses that kind, so they never instantiate.
They're kept and marked `[[maybe_unused]]`, since deleting them would
break any future bitfield option.

NFC.

Part of #202945.
