Add action shortcut mapping for KEYCODE_DPAD_CENTER

• I have checked that a similar feature request does not already exist.

Is your feature request related to a problem? Please describe.
I'm trying to control my TV with scrcpy. The TV do respond to HOME(middle mouse) and BACK(right mouse) action, as well as navigation(Arrow keys). But its UI and native apps do not respond to either click or Enter (though installed third-party apps like kodi does) when I want to press the button in focus. After some testing, I find that manually running adb shell input keyevent KEYCODE_DPAD_CENTER does the job. So...

Describe the solution you'd like
Mapping left click or Enter to such keyevent

Describe alternatives you've considered
Implementing #4569 can do that?

It does not respond to clicks? 😮

What about SPACE? and (out of curiosity) AKEYCODE_NUMPAD_ENTER?

@rom1v I do find it very strange, because it does seem to respond to a physical mouse's clicks. I will try what you suggested later.

OK so it works in UHID mode? (scrcpy -M)

[dzx-dzx]

No...which is even more confusing to me. Upon reading the description I did expect it to function, but it didn't.

What about SPACE?

Oh, SPACE does work...partially. It(which maps to KEYCODE_SPACE?) only works on the main screen.
