[fabric] Add conditional coordinate space conversion for native view …

…hit testing

Summary:
Native views use the AppKit api for hit testing which requires the point to be in the superview coordinate system.

This diff updates the hit testing in `RCTViewComponentView` to conditionally converts the point to the target view coordinate system only if the tested view is a react view.

Test Plan:
Run Zeratul with Fabric and select text inside message bubbles. The scroll view being a native view, the hit testing does not require a point conversion. With this change, the text selection works as expected.
