PY-70729: Move `com.jetbrains.extensions` deprecated package to the separate module.

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

(cherry picked from commit ac83deba61735dd09c2c7133fdca37605480f654)
