To workaround some issues with transcoded file sizes transferred
via MTP on Windows machines, we restart the MTP connection after
changing the transcode flag.

Enabling "Transcode exported media" means that the media transferred
from the device via MTP over USB would be transcoded, if necessary. This
switch also sets / unsets the sys.fuse.transcode_mtp system property.
"Transcode exported media" category would be accessible only when the
"File transfer / Audio Auto" or "PTP" radio button has been selected. We
are including PTP also since PTP supports transfer of videos.
Adding UsbDetailsTranscodeMtpController in a separate preference
category than "Charge connected device" primarily because they seemed to
be different in their own rights.
