Trim whitespace and refactor AlsoNotify property handling

Removed trailing whitespace in generated property setters across multiple test verification files. Refactored AlsoNotify property handling in the source generator to filter and add valid property names more efficiently, and simplified the code for generating AlsoNotify attributes. Updated a test summary for clarity.
