Tokenizer/PHP: bug fix for static typed properties with union/intersection types

Just like the `var` keyword, the `static` keyword can also be used stand-alone with property declarations.
https://3v4l.org/sbaDM

In that case, the tokenization of the `|` operator was not changed to `T_TYPE_UNION` and the `&` operator was not changed to `T_TYPE_INTERSECTION` as the `static` keyword can also be used in return type declarations, so was seen as part of the type declaration.

Fixed now by removing the `T_STATIC` token from the `$allowed` list before walking backwards from the operator.

Includes tests.
