Call clang-tidy with -fno-caret-diagnostics by default.

* clang -fno-caret-diagnostics
  suppresses warning source lines, carets, and
  the stats line of "n warnings generated"
* clang-tidy -extra-arg-before=-fno-caret-diagnotics
  only suppresses the "n warnings generated" line.
* Pass this flag and -quiet to clang-tidy when
  WITH_TIDY is not 1 or true.
* Remove redundant quotation marks around -extra-arg-before.

Bug: 69051430
