Paste on "set clipboard" if possible

Browse Source 
Ctrl+Shift+v synchronizes the computer clipboard to the Android device
clipboard. This feature had been added to provide a way to copy UTF-8
text from the computer to the device.

To make such a paste more straightforward, if the device runs at least
Android 7, also send a PASTE keycode to paste immediately.

<https://developer.android.com/reference/android/view/KeyEvent.html#KEYCODE_PASTE>

Fixes #786 <https://github.com/Genymobile/scrcpy/issues/786>
