Pull request overview

This PR improves the public API documentation for a set of AppKit enum types by replacing placeholder XML docs with real summaries, and then removes the corresponding type entries from the Cecil documentation known-failures list (since they should no longer fail documentation validation).

Changes:

• Added <summary> XML docs for 10 AppKit enum types and their members in src/AppKit/Enums.cs.
• Removed the corresponding T:AppKit.* entries from tests/cecil-tests/Documentation.KnownFailures.txt.

File summaries

File	Description
src/AppKit/Enums.cs	Replaces placeholder enum/member docs with descriptive XML summaries for the 10 listed AppKit enums.
tests/cecil-tests/Documentation.KnownFailures.txt	Removes known-failure type entries for the enums now documented.
