ada-lang.c: Introduce type_as_string and use it

A couple wrong things here

  - We should not use target_terminal_ours when all we want is output.
    We should use target_terminal_ours_for_output instead, which
    preserves raw/cooked terminal modes, and SIGINT forwarding.

  - Most importantly, relying on stderr output immediately preceding
    the error/exception print isn't correct.  The exception could be
    caught and handled, for example; MI frontends won't display the
    stderr part in an error dialog box.  Etc.

This commit introduces a type_as_string helper that allows building a
full error string including type info.
