Pause on error from a wrapper script

On Windows, scrcpy paused on error before exiting to give the user a
chance to see the user message.

This was a hack and causes issues when using scrcpy from batch scripts.

Disable this pause from the scrcpy binary, and provide a batch wrapper
(scrcpy-console.bat) to pause on error.
