[MacOS] Fix Pressable being unresponsive (#3142)

## Description

This PR fixes incorrect `Pressable` behaviour on `MacOS`, which was
caused by the following sub-issues:

- Pointer tracker on `MacOS` kept returning incorrect relative
coordinates.
This was caused by converting the `absolute` coordinates from the
`local` coordinate space to the `absolute` coordinate space instead of
the other way around.

- There was no workflow set on the `Gesture.Native()` to allow for
activation of `Pressable`

## Test plan

- Open any `Pressable` example on `MacOS`
- See how they all should work now.
