[desktop] port IR Camera to Qt6 & fix camera saving on windows (#3630)

Browse source 
The camera was previously saved without escaping the name which made the values unusable after a settings load, for whatever reason replacing the backslashes when saving with / doesn't work but replacing them with | does.

Also note that the OBS virtual cam (and any other cameras that only have directshow drivers) won't work because Qt6 dropped support for that and the ffmpeg backend doesn't seem to support it either.

Closes #3468
