Add Launcher hover effect

Use Launcher iconlib's FastBitmapDrawable for chooser item icons to
enable the Launcher pointer hover effect.

Add a custom ChooserTargetItemView to dispatch hover events.

Modify the chooser item layout to use the new view and replace image
view margins with paddings to accommodate scaled-up icons on hover.

Bug: 295175912
Test: atest IntentResolver-tests-unit
Test: manual testing for icons hover effect including the case of
disabled icons when no selections is made in Shareousel
Flag: com.android.intentresolver.target_hover_and_keyboard_focus_states
