Chandler CarruthandGeoff Romer 2b9fdd6e42 Fix the check that every registered diagnostic kind is declared (#7660 )

`load_diagnostic_kind` matched `^\s+CARBON_DIAGNOSTIC_KIND` without
`re.MULTILINE` against a file whose entries start at column zero, so it
found nothing: `check_unused` was comparing an empty set of declarations
against every use and reporting nothing at all. The check has never run.

With it running, three kinds turn out to be registered and never
declared, and go: `BuildFailureRunningClangToLink`,
`BuildOutputFileOpenError`, and `BuildPreludeManifestError`.

`load_diagnostic_uses_in` looked only for `CARBON_DIAGNOSTIC`, so a
diagnostic declared with `CARBON_DIAGNOSTIC_ON_SCOPE` counted as unused,
and it read the two macros' own definitions in `diagnostic.h` as uses.
Both are why the kinds above could not simply be deleted before.
