Refactor the design and improve the animations of Accessibility Floating Menu(4/n).

Actions of this change:
1) Add default or restore values for the start position.
2) Customize the available bounds of the accessibility floating menu depending on the floating menu bounds, margin, and the window insets of the navigation bars, status bars, and display cutout.
3) Apply view-based animations for translation.
4) Exclude the system gestures area and customize the touch region to avoid it conflict with the floating menu and block the touch events.
