[gdb] Handle ^C in gnu_source_highlight_test

Browse Source 
In gnu_source_highlight_test we have:
...
  try
    {
      res = try_source_highlight (styled_prog, language_c, fullname);
    }
  catch (...)
    {
      saw_exception = true;
    }
...

This also swallows gdb_exception_quit and gdb_exception_forced_quit.  I don't
know whether these can actually happen here, but if not it's better to
accommodate for the possibility anyway.

Fix this by handling gdb_exception explicitly, and rethrowing
gdb_exception_quit and gdb_exception_forced_quit.

Tested on aarch64-linux.
