[flang][driver] Fine-tune `-fdebug-dump-symbols`

When generating output for `-fdebug-dump-symbols`, make sure that
BuildRuntimeDerivedTypeTables is also run. This change is needed in
order to make the implementation of `-fdebug-dump-symbols` in
`flang-new` consistent with `f18`. It also allows us to port more tests
to use the new driver whenever it is enabled.
