Fix WM input limitations on secondary displays (2/4)
- Change setInputWindow of InputManagerService to carry displayId,
so InputWindowHandle can be updated by each DisplayContent.
- If focus window exist in current display, we need to reset it to nullptr
in the intermediate state before the new focus set,
to prevent it will access the released info.
- use INDENT2 for dump window under display, and likewise below.
- Some test cases for setInputWindow
