This adds a recovery mode to the diagnostics so that we can

attempt to recover from a corrupted profile.

Currently, the only recovery that is attempted is recovering from a
corrupted NSS database on ChromeOS.

(TBR'ing trivial OWNERS review for added switch constants in chromeos dir)

TBR=stevenjb@chromium.org
BUG=chromium:236093
TEST=ran against corrupted nss db files.  Ran unit test.
