Subject: Add keboard focus outline for Chooser targets

This change applies the same focus outline as Launcher but the end
result still needs more polishing. Some noticeable issues are:
* the outline may overlap with a long label;
* targets with a one-line labels look adjusted to the top and not
  centered;
* with the light system ui theme, the outer online frame is barely
  visible compare to the inner outline (this is also true for Launcher).

Bug: 295175912
Test: visual effect testing
Flag: com.android.intentresolver.target_hover_and_keyboard_focus_states
Change-Id: I1d22b187e0cc4b95c385d4f5b956effa31fd4505
