feat: add platform glob scope support

[BryanttV]

Resolves: openedx/openedx-authz#268

Description

This PR adds support for a platform-wide scope (PlatformCourseOverviewGlobData) when resolving AuthZ permissions in Studio, so users with global access can see all courses where the AuthZ course-authoring feature flag is enabled.

Additionally, extends the course creation permission check (course.create_courses) to accept both platform-wide and organization-scoped permissions.

Hello @BryanttV, thanks for this PR.

Regarding the functionality, this works as expected! ✅

I review it, and it looks good, just a small comment.

And to verify the test pass, we should use the hash of your last commit in openedx-authz (then you can change it again to v1.16.0).
