Fix -fdump-ada-spec

After changes by Sharad (Add option for dumping to stderr (issue6190057)),
-fdump-ada-spec is broken, and is now a no-op.

Admittedly, this is because -fdump-ada-spec is handled differently from
other -fdump-* switches, so this patch fixes support for -fdump-ada-spec
by using an approach similar to -fdump-go-spec, and use regular switches
via c/c.opt. I've removed the handling of TDF_RAW, which was a debugging
option, and never really used, so can be simply deleted.

Change is mostly trivial/mechanical.

Tested on x86_64-pc-linux-gnu, OK for trunk?

Much cleaner indeed.

Ok,
Thanks,
