Disable the use of CGDisplayStreamCreate() for desktop capture on Sonoma

CGDisplayStreamCreate is an deprecated API. It was believed that the use
of it was disabled on Sonoma through the setting allow_iosurface = false
[1], which causes the thumbnails to be created by the API CGDisplayCreateImage.
This API is not marked as deprecated at the moment.

However, although the thumbnails are created through CGDisplayCreateImage,
CGDisplayStreamCreate() is still called and runs in the background.
This makes the capture chip appear.

No capture chip appears if this CL is landed and the ScreenCaptureKit
thumbnail capturer is enabled,
--enable-features="ScreenCaptureKitMac,ScreenCaptureKitStreamPickerSonoma,ThumbnailCapturerMac:capture_mode/sc_screenshot_manager"
