Pressability: fix typo in variable, follow event check pattern, small tweak (#30151)

Summary:
This small PR introduces the following changes to the `Pressability`:
* fixes typo in internal `isActivationTransiton` variable name
* assigns `onPressMove` to variable before check and potential usage (this is the common pattern in this file)
* utilizes destructuring assignment to simplify passing coordinates to `_touchActivatePosition`

## Changelog
