Make pressing and moving on CupertinoButton closer to native behavior. (#161731)
Fixes: #91581 

This PR adds an `onTapMove` event to `TapGestureRecognizer`, and then
`CupertinoButton` uses this event to implement the behavior of the
native iOS `UIButton` (as shown in the issue). It is worth noting that
this PR slightly changes the way `CupertinoButton`'s `onPressed` is
triggered. Specifically, it changes from being triggered by
`TapGestureRecognizer`'s `onTap` to checking if the event position is
still above the button in `TapGestureRecognizer`'s `onTapUp`.
Additionally, it removes the previous behavior where the gesture was
canceled if moved beyond `kScaleSlop` (18 logical pixels). Overall,
previously, `onPressed` could not be triggered if the button was pressed
and then moved more than 18 pixels. This PR adjusts it so that
`onPressed` cannot be triggered if the button is pressed and then moved
outside the button.

Tests for the Cupertino package

Avoid importing the Material 'package:flutter/material.dart' in these tests as we're trying to test the Cupertino package in standalone scenarios.

The 'material' subdirectory contains tests for cross-interactions of Material Cupertino widgets in hybridized apps.

Some tests may also be replicated in the Material tests when Material reuses Cupertino components on iOS such as page transitions and text editing.
