c++: Fix ICE after ambiguous inline namespace reopen [PR94257]

Following DR2061, 'namespace F', looks for 'F's inside inline namespaces.
That can result in ambiguous lookups that we failed to diagnose early
enough,
leading us to push a new namespace and ICE later.  Diagnose the ambiguity
earlier, and then pick one.

PR c++/94257
* name-lookup.c (push_namespace): Triage ambiguous lookups that
contain namespaces.

This compiled without errors until
r8-952-g945bf9e13f706bed44ec760ac60693e00c59b146:

94257.C:4:18: error: conflicting declaration of namespace ‘B’
 inline namespace B {
  ^

and the ICE started with 
r8-1488-g71bbbd133f65c26f65709037401154362210560e
