Fixed an issue where toggling the Incremental GC or active input handling player settings and then restarting the editor didn't result in the new setting taking effect.
Fixed build profile virtual texturing issues: 1. Updating the player setting value didn't get serialized to the asset file. 2. Toggling the virtual texture player setting for an inactive profile still showed the restart editor prompt. 3. Even after restarting the editor, we didn't update EditorOnlyVirtualTextureState.json that the PlayerSetting methods used as the source of truth for the setting, which resulted in a subsequent restart prompt appearing as the project was opening after the initial restart.
