fix Issue 14965 - Forward reference to inferred return type of function call
when using auto return type

If a function symbol is used, its overload resolution should be deferred until:

```d
func(...)           // CallExp.semantic
func.mangleof       // DotIdExp.semanticY
typeof(func)        // TypeTypeof.resolve
typeof(&func)       // TypeTypeof.resolve
auto v = &func;     // ExpInitializer.inferType
&func;              // ExpStatement.semantic
return &func;       // ReturnStatement
```

When the semantic analysis reaches to them, the function forward reference can
beome actual error.

Other use of 'func' should be treated as a property-like function call (done in
`resolveProperties`) and finally handled in `CallExp`.
