This package is only used by third party plugins. We can't leave it inside another v2 module due to package inconsistency.

See errors like https://youtrack.jetbrains.com/issue/PY-70729/Class-com.jetbrains.python.psi.PyElementType-must-not-be-requested-from-main-classloader-of-Pythonid-plugin#focus=Comments-27-9494155.0-0

So we move it to the separate v2 module which will be removed soon
