Type::toPhpDocNode() returned a plain IdentifierTypeNode for both keywords (int, mixed, non-falsy-string) and class names, so consumers had to guess which was which and how to print or import it.

This now uses phpdoc-parser 2.4's NameNode, FullyQualifiedNameNode and RelativeNameNode (phpstan/phpdoc-parser#339, pulled in by #6877). They don't extend IdentifierTypeNode, so PHPStan doesn't ship its own copies any more.

Commit 1: handle name nodes when resolving PHPDocs. With phpdoc-parser 2.4, 2.3.x currently has 7 make phpstan errors where code reads ->name from a node that can now be a NameNode. This commit fixes them:

• TypeNodeResolver resolves a name node as a class against the name scope, before keywords, type aliases and template types. A RelativeNameNode('Int') in namespace App is the class App\Int, while IdentifierTypeNode('Int') is still int.
• PhpDocNodeResolver (@extends, @implements, @use, @phpstan-import-type) and IntersectionType::toPhpDocNode() (PHP and turbo) no longer assume an IdentifierTypeNode.

Commit 2: return name nodes from toPhpDocNode().

• ObjectType, GenericObjectType, ClosureType and GetTemplateTypeType return FullyQualifiedNameNode, and EnumCaseObjectType a fully qualified ConstFetchNode. A printed node resolves to the same class in any namespace and with any uses. Keywords, pure-/static-Closure and template type names stay IdentifierTypeNode.
• describe() output is unchanged: TypeNodeDescriber prints names without the leading backslash. That also covers OffsetAccessType and LateResolvableArrayShapeType.
• The turbo extension returns the same nodes. The now-unused Printer class ref is gone; fullyQualifiedNameNode is a new one.

Rector counterpart (local prototype, not opened yet): with these nodes Rector can delete its whole PHPStanStaticTypeMapper package (all 30 mapToPHPStanPhpDocTypeNode() mappers), about −1750 lines, with its full test suite green after a small style pass and 14 fixtures with equivalent output.
