According to the AVCaptureDevice documentation, the device must be
locked before starting the capture session to prevent the activeFormat
from being overridden. We now do that, but only if we explicitly set
an activeFormat. Otherwise the device is not locked, which allows
the session to find an appropriate format for the capture device.
The device is also locked when enabling video capture, as doing so
might also reset the activeFormat.

Image capture resolution and viewfinder resolution must be the same,
with the image capture resolution taking precedence over the viewfinder
resolution when both are explicitly set.
The code was getting the active image capture resolution, instead of
the one explicitly requested, to adjust the viewfinder resolution.
That effectively made the viewfinder resolution always ignored since
the active capture resolution always has a default value.

It was hardcoded to ARGB32, which is not a good idea, at least on iOS
where the necessary conversion is slow.
We now pick the QAbstractVideoSurface's preferred format, or if no
surface is set, we pick the default from AVFoundation.
As a result, the QML VideoOutput will now always use the NV12 format.

The microphone permission was always requested when using the camera,
even when not actually using the microphone, which can only happen when
recording a video. The permission request is triggered by adding an
audio AVCaptureDeviceInput to the AVCaptureSession, which was done when
setting the camera to LoadedState. This is now done when setting the
camera mode to CaptureVideo.

Excluding video range (iOS) is not the right way to avoid "duplicates" - with
other devices there can be also duplicates (formats with the same resolutions),
but completely different pixel formats. Since we do not know what they will be in advance,
we take the media subtype from the initial preset for a capture device and use it
as a filter. Update viewfinder and image encoder settings controls.

The reference counting was not being done for AVCaptureSession so it was
being destroyed before we got a chance to properly clean it up (which
lead to crashes). We also make sure to remove any observers from
AVCaptureSession now before destroying it.
