  [C++20] [Modules] Use current named module to do module local lookup

See the attached test for the motiviation.

Previously we dependent on the module ownership of the decl context to
perform module local lookup. But if the lookup is unqualified, we may
perform the lookup with canonical decl, which belongs to the incorrect
named module
