[DWARF] Generalize DWARFTypePrinter to a template class (#109459)

This generalizes DWARFTypePrinter class to a template class so that it
can be reused for lldb's DWARFDIE type.

This is a split of #90008. The
difference is that this doesn't have `Visitor` template parameter which
can be added later if necessary.
