Add option to disable clipboard autosync

By default, scrcpy automatically synchronizes the computer clipboard to
the device clipboard before injecting Ctrl+v, and the device clipboard
to the computer clipboard whenever it changes.

This new option --no-clipboard-autosync disables this automatic
synchronization.
