The libcamerasrc gstreamer component does seem to not allow stream resolutions
that are not advertised by PipelineHandler::generateConfiguration(). This has
been raised in a bug report [1].
Fix this behavior by advertising a SizeRange from the minimum ISP resolution, up
to the sensor resolution from PipelineHandlerRPi::generateConfiguration().

We clear the V4L2_CID_HFLIP and V4L2_CID_VFLIP controls immediately
after opening the camera device. This means the camera's Bayer format
and mbus codes will be in the sensor's "native" order, and we document
this to be the case so that it can be relied upon.
Clearing the flips is harmless where sensor flips do not affect the
Bayer order.
This also fixes a bug in the Raspberry Pi pipeline handler where the
native Bayer order was being computed wrongly, but the new behaviour
here will be helpful to other pipeline handlers too. A subsequent
commit will tidy up the Raspberry Pi pipeline handler in this area as
it can now be simplified.

Previously this helper was not necessary, as (with respect to the

so the other template generators that used the preview template as
boilerplate could reliably use updateEntry(). The preview template
