Update access_rule structure for Moodle 4.2+

[TomoTsuyuki]

I got an error when running unit test for plagiarism_turnitin.

1) plagiarism_turnitin_quiz_testcase::test_update_mark
Unexpected debugging() call detected.
Debugging: This file is no longer required in Moodle 4.2+. Please do not include/require it.

Moodle updated the quiz_access_rule_base class to mod_quiz\local\access_rule_base from Moodle 4.2.

Plugins for Moodle 4.2+ should use mod_quiz\local\access_rule_base.
