feat: support keyboard gesture on mobile

[LucasXu0]

• [x] iOS: Ignore the text update when moving the cursor using the space bar. Only update the text delta when movement ends.
• [x] Android: Some keyboards use nonTextUpdate to implement keyboard gestures, while others use onFloatingCursor. So we should support both of them.
