Eli White 9cc920be2f Pressability: Support Rect or Numeric Size
Summary:
Introduces `Rect`, an (eventual) replacement for `EdgeInsetsProp`.

This new type is then used in `Pressability` to expand support such that `hitSlop` and `pressRectOffset` can be either a `Rect` or a numeric size.

Changelog:
[Internal]
