Also build "noconsole" binary for Windows

On Windows, an application is either console or gui, it cannot be both.

Scrcpy should be both: it outputs important information to console, but
we still want to be able to ignore the console and launch it without a
visible cmd.exe window.

Therefore, build two binaries:
 - scrcpy.exe
 - scrcpy-noconsole.exe
