[Course Settings] Link Validator should detect assignment conflicts and access issues with new Assign To functionality

[abbyrosensweig]

Problem statement:

If an item is assigned to a subset of students but then posted somewhere else that is assigned to a different subset of students, the instructor would not receive a warning that students might not have access to the assigned item. For example, if a Page has a course link to a Quiz and the Page and Quiz are assigned to different sections, students won’t be able to access the Quiz from the Page. There should be a warning or that should register in the Link Validator.

Proposed solution:

Have Link Validator include a scan of the assignment(s) associated with course items to detect any possible conflicts. For example, if a quiz for Section A is in a module assigned only to Section B, the Link Validator should flag that as a potential problem.
