[Sanitizer] Parse and produce all sanitizer-relevant arguments in SanitizerArgs.

In particular, make SanitizerArgs responsible for parsing
and passing down to frontend -fsanitize-recover and
-fsanitize-undefined-trap-on-error flags.

Simplify parsing -f(no-)sanitize= flags parsing: get rid of
too complex filterUnsupportedKinds function.

No functionality change.
