Pavel Lang 09f738c6d5 [graphql] Predicates can be now used as type guards (#31701) ...

* feat(graphql): predicates as type guards

Predicates in `graphql/language/predicates` are used in Flow as type
guards.
Now they can be used in TS too:

* isDefinitionNode
* isExecutableDefinitionNode
* isSelectionNode
* isValueNode
* isTypeNode
* isTypeSystemDefinitionNode
* isTypeDefinitionNode
* isTypeSystemExtensionNode
* isTypeExtensionNode

* chore(graphql): add langpavel to "Definitions by"
