[4/n] Add an API to disable edge resizing for tiling.

This change updates DesktopModeWindowDecoration with an new API,
updateDisabledResizingEdge, that disables a resizing edge including its
corners for finger, mouse and styles gestures.

This is needed because on tiling a task on the left, its right resizing
edge should be disabled, and on tiling a task on the right, its left
resizing edge should be disabled.

Flag: com.android.window.flags.enable_tile_resizing
Test: tests are WIP
