fix(Menu): Do not rely on tabster restorer for focus restore

[ling1726]

The restorer can cause unintended focus switching whenever other restore sources lose focus to body. In internal discussions with @jurokapsiar we decided that it would be better to allow lost focus to body in applications rather than unexpected focus switches.

There are no changes to Popover or Dialog because those previously used Deloser as a part of attributes and there was never imperative focus restore on those components

Previous Behavior

The Menu used Tabster Restorer API to restore focus to the trigger

New Behavior

Reverts Menu to restore focus manually pre - #28530. However the restorer source is still kept on the MenuPopover to make sure that users can still use Menu without a trigger easily.
