Desktop: Support input from drawing tablets (#4354)

* Rename the editor mouse state types to Pointer* and the input_ modules

* Add optional pen attributes to the editor pointer state types

* Desktop: Send tablet pointer clicks to CEF as mouse clicks

* Desktop: End pointer lock and pending window drags on any left-equivalent release

* Desktop: Route pointer input carrying pen attributes directly to the editor

* Desktop: Route wheel and pinch input inside the viewport directly to the editor

* Desktop: Track double clicks on the direct editor route

* Desktop: Move the pointer lock position into InputState

* Restore the input state pointer position when pointer lock ends (review)

* Fix pen input being swallowed by Windows resize helper

* Update winit to 0.31.0-beta.2 from crates.io
