[Screen Ruler] Improve UX (#20400)

* [Screen Ruler] add 7% opacity to tooltip background

* [Screen Ruler] restrict mouse cursor to monitor while in bounds mode

* [Screen Ruler] Do not preview overlay ui on all virtual desktops (Win + tab)

* [Screen Ruler] add hotkeys for toolbar #20345

* [Screen Ruler] Make single snapshot capture mode a default and update warning

* [Screen Ruler] Fix touch input in bounds mode #20286

* [Screen Ruler] activate window and set HWND_TOPMOST flag again after initialization
