The V4L2DeviceFormat structure for the ISP Output 1 node was a copy of what is
used ISP Output 0 node, but with the size changed. However, the plane size and
stride values were not updated. So there is a possibility that the buffer might
be over-sized for the requested resolution.
Fix this by only copying the relevant fields from the ISP Output 0
V4L2DeviceFormat structure, and let the device driver size the planes as needed.

The start(unsigned int msec) overload is error-prone, as the argument
unit can easily be mistaken in callers. Drop it and update all callers
to use the start(std::chrono::milliseconds) overload instead.
The callers now need to use std::chrono_literals. The using statement
could be added to timer.h for convenience, but "using" is discouraged in
header files to avoid namespace pollution. Update the callers instead,
and while at it, sort the "using" statements alphabetically in tests.

The RkISP1Path::generateConfiguration() function limits the maximum
resolution to the sensor resolution, to avoid upscaling. It however
doesn't take the sensor aspect ratio into account, which leads to a
maximum (and default) resolution of 1920x1920 when using the self path
with a sensor that has a higher resolution.
Fix it by constraining the minimum and maximum resolutions to match the
sensor's aspect ratio.

The IPARkISP1Interface currently uses event-type based structures in
order to communicate with the pipeline-handler (and vice-versa).
Replace the event based structures with dedicated functions associated
to each operation.
The translated naming scheme of operations to dedicated functions:
ActionV4L2Set => setSensorControls
ActionParamFilled => paramsBufferReady
ActionMetadata => metdataReady
EventSignalStatBuffer => processStatsBuffer()
EventQueueRequest => queueRequest()
The lexical of IPARkISP1::metadataReady() will now conflict with the
metadataReady Signal being introduced in this patch as part of the
interface change. Hence, rename IPARkISP1::metadataReady() to
IPARkISP1::prepareReady() to prevent the conflict.

Since VCM for surface Go 2 (dw9719) had been successfully driven, this
Af module can be used to control the VCM and determine the focus value
based on the IPU3 AF state.
Based on the values from the IPU3 AF buffer, the variance of each focus
step is determined and a greedy approach is used to find the maximum
variance of the AF state and an appropriate focus value.
The grid configuration is implemented as a context. Also, the grid
parameter- AF_MIN_BLOCK_WIDTH is set to 4 (default is 3) since if the
default value is used, x_start (x_start > 640) will be at an incorrect
location of the image (rightmost of the sensor).

Objects are not expected to be connected to the same signal more than
once. Doing so likely indicates a bug in the code, and can be
highlighted in debug builds with an assert that performs a lookup on the
signals_ list.
While it is possible to allow the implementation to let objects connect
to a specific signal multiple times, there are no expected use cases for
this in libcamera and this behaviour is restricted to favour defensive
programming by raising an error when this occurs.
Remove the support in the test framework which uses multiple Signal
connections on the same object, and update the test to use a second
Signal.
