dbghelp: Let symt_basic be trans-module and nameless.

Rationale: - native doesn't report names for SymTagBaseType objects => so remove typename for sym_basic - since symt_basic becomes pretty simple, it's possible to share the object across all modules loaded in dbghelp (simplicity, memory usage reduction) - removed dwarf basic types cache in dwarf.c as we now have a generic one Signed-off-by: 's avatarEric Pouech <eric.pouech@gmail.com> Signed-off-by: 's avatarAlexandre Julliard <julliard@winehq.org>
