[Driver] Improve unused-argument diagnostic for extra sanitizer features.
Don't print unused-argument warning for sanitizer-specific feature flag
if this sanitizer was eanbled, and later disabled in the command line.
For example, now:
clang -fsanitize=address -fsanitize-coverage=bb -fno-sanitize=address a.cc
doesn't print warning, but
clang -fsanitize-coverage=bb
does. Same holds for -fsanitize-address-field-padding= and
-fsanitize-memory-track-origins= flags.
Fixes PR23604.
