Support auto import for traits in all scopes

[daltones]

Feature description or problem with existing feature

Currently, PHP Intelephense offers auto import for traits only after the use keyword (inside a class-like scope).

However, it is valid to call a static method from a trait anywhere. Or maybe you just need to reference the trait's FQCN somewhere (like in MyTrait::class).

It's worth noting that, once the trait is already imported, auto-complete works perfectly when calling trait static methods.

Describe the solution you'd like

<?php

namespace MyNamespace;

trait MyCoolTrait {
    public static function someMethod() {}
}

<?php

namespace MyOtherNamespace;

class MyClass {
    public static function doSomething(): void {
        MyCoolTr // auto-complete/auto-import would be wonderful here!
    }
}
