libstdc++: Fix flat_map::operator[] for const lvalue keys [PR120432]
The const lvalue operator[] overload wasn't properly forwarding the key
type to the generic overload, causing a hard error for const keys.
Rather than correcting the forwarded type this patch just makes the
non-template overloads call try_emplace directly instead. That way we
can remove the non-standard same_as constraint on the generic overload
and match the spec more closely.

libstdc++-v3/ChangeLog:
* include/std/flat_map (flat_map::operator[]): Make the
non-template overloads call try_emplace directly. Remove
non-standard same_as constraint on the template overload.
* testsuite/23_containers/flat_map/1.cc (test08): New test.
