update version of edx-proctoring library to 2.5.13

[AA-497] Only set due dates on subsections that contain graded assignments with a score and a nonzero weight

Deprecated edx-platform import paths
(for example, `student` instead of
`common.djangoapps.student`) currently raise
warnings when used. We want to fully remove
support for those paths.

As an easily reversible way to initially remove
support, we add a new setting to LMS and Studio
called `ERROR_ON_DEPRECATED_EDX_PLATFORM_IMPORTS`,
defaulting to False. We set it to True for devstack
and will set it to True in Stage and Production
soon. If critical errors occur, we can easily
flip the setting back to False.

The correct path is `common.djangoapps.course_modes...`

* Upgrade social-auth-core

Previously we were only checking the graded attribute which doesn't account for ungraded assignments

edx-enterprise version bump.

This PR lays the groundwork for a an LTI tab that can embed any LTI1.1-based
tool as an course tab. It also adds another tab based on this LTI Tab that
offers special support for embedding LTI-based discussion tools in a course
tab. If enabled this will replace the existing discussion tab.
