Simplify error messages and implementation for internal errors (#3881) 
* Use more consistent language for Internal errors

There's no meaningful distinction between something being internal and
being 'marked as internal'.

* Rename property psalm_internal to internal in all storage classes

This property holds metadata that can be set using either @internal
or @psalm-internal in docblocks

* Change types of internal properties in storage from ?string to string

Simpler type is easier to handle. Non-internal methods can be considered
to be internal to the entire universe of PHP code, i.e. that code whose
namespace starts with the empty string. It's not a special case.

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
