Fix multiple issues with @internal and @psalm-internal (#3841)
* Add passing tests for property fetch on an @internal class

I'm trying to work out why the equivilent InvalidCodeParse test is
failing for PsalmInternal

* Treat all properties of a psalm-internal class as psalm-internal

* Remove all $internal properties from storage - use psalm_internal instead

@internal can be represented as internal to the namespace root, avoiding
the need to check for both properties in storage later.

* Raise InternalClass issue when an internal class is used with e.g. instanceOf

* fix docs and tests

* Add return type declartion to code example in doc

* Don't allow class psalm-internal to overide a tighter method psalm-internal

* Break up long line

* Code style - move && from EOL to SOL

* Restore misplaced &&

* Fix code style

* Fix namespace fetching so it works

# InternalClass
Emitted when attempting to access a class marked as internal an unrelated namespace or class, or attempting
to access a class marked as psalm-internal to a different namespace.
```php
<?php
namespace A {
/**
* @internal
*/
class Foo { }
}
namespace B {
class Bat {
public function batBat(): void {
$a = new \A\Foo();
}
}
}
```
