[0.22] Remove PointerEvent fallback

[zoontek]

Important

This PR targets the 0.22-dev branch

The new browser targets all support PointerEvent, so this PR removes the mouse / touch fallback paths.

react-native-web

• useHover now always listens to pointerenter, pointermove and pointerleave, and reads e.pointerType directly
• useHover drops the x / y polyfill on hover events (available since Chrome 55)
• useHover uses new CustomEvent() in place of initCustomEvent (deprecated)
• Removes the modality module. Its only use was to guess the pointer type when PointerEvent was not available

dom-event-testing-library

• Removes describeWithPointerEvent, hasPointerEvent and setPointerEvent
• Event sequences now always dispatch pointer events
• testWithPointerType always runs for mouse, touch and pen
• Updates the README to match. It also adds the missing error, load and pointerup event entries, and documents clearPointers.
