Implement DAP setExceptionBreakpoints request

This implements the DAP setExceptionBreakpoints request for Ada.  This
is a somewhat minimal implementation, in that "exceptionOptions" are
not implemented (or advertised) -- I wasn't completely sure how this
feature is supposed to work.

I haven't added C++ exception handling here, but it's easy to do if
needed.

This patch relies on the new MI command execution support to do its
work.
