c++/modules: Propagate purview/import for templates in duplicate_decls [PR116803]
We need to ensure that for a declaration in the module purview, that the
resulting declaration has PURVIEW_P set and IMPORT_P cleared so that we
understand it might be something requiring exporting. This is normally
handled for a declaration by set_instantiating_module, but when this
declaration is a redeclaration duplicate_decls needs to propagate this
to olddecl.
This patch only changes the logic for template declarations, because in
the non-template case the whole contents of olddecl's DECL_LANG_SPECIFIC
is replaced with newdecl's (which includes these flags), so there's
nothing to do.
PR c++/116803

* decl.cc (duplicate_decls): Propagate DECL_MODULE_PURVIEW_P and
DECL_MODULE_IMPORT_P for template redeclarations.
