  Reject out-of-bounds enum sentinels in DenseMap/DenseSet. (#150308)

This makes the bug in PR #125556 which was fixed by
dc87a14efb381d960c8fbf988221f31216d7f5fd into a compile-time error.

...and fix a newly-discovered instance of this issue, triggered by a
`llvm::MapVector<AccessSpecifier, ...>` in
clang-tools-extra/clangd/refactor/tweaks/OverridePureVirtuals.cpp.
