* 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.
* 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

* Fix going to definition on return type
If a return type of a method or function is set incorrectly (with the PHP doc), then the references are not added for the `function() : MyClass` symbol, so the "Go to definition" feature of the LSP won't work. I don't believe an invalid return type or not should stop the symbol location being tracked (and not allowing code navigation).
In moved the symbol location tracking to be before the return early short circuit.
* Update SymbolLookupTest.php

Currently it's not possible to "Go to definition" (LSP) on nullable args like `function( ?MyClass )` as the reference is stored a `MyClass|null` in the reference map, which will now resolve to a class name.
This PR removed any nullable type from the union before adding it to the reference map (as the reference map is only use to indicate a symbol was used in a given location, I think this makes sense).
