  Resolve forward reference in `VarDeclaration.toAlias()`

After this change:
1. The check `!v.type` in `DsymbolExp.resolve` and `ScopeExp.semantic` will mean *unresolvable* forward reference.
2. The code for issue 12023 in `DsymbolExp.resolve` becomes cleaner.
3. Through the calls `AliasDeclaration.toAlias` and `VarDeclaration.toAlias`, selected import symbols will be resolved and `ice11300.d` case is made compilable.
