Extend the Algorithm::process() function with a metadata control list,
to be filled by individual algorithms with frame metadata. Update the
rkisp1 and ipu3 IPA modules accordingly, and drop the dead code in the
IPARkISP1::prepareMetadata() function while at it.
This only creates the infrastructure, filling metadata in individual
algorithms will be handled separately.

Frame contexts will become the core component of IPA modules, always
available to functions of the algorithms. To indicate and prepare for
this, turn the frame context pointer passed to Algorithm::process() into
a reference.
The RkISP1 IPA module doesn't use frame contexts yet, so pass a dummy
context for now.
While at it, drop an unneeded [[maybe_unused]] from Agc::process() and
add a missing parameter documentation for the frameContext argument to
Awb::process().

Currently we have a single structure of IPAFrameContext but
subsequently, we shall have a ring buffer (or similar) container
to keep IPAFrameContext structures for each frame.
It would be a hassle to query out the frame context required for
process() (since they will reside in a ring buffer) by the IPA
for each process. Hence, prepare the process() libipa template to
accept a particular IPAFrameContext early on.
As for this patch, we shall pass in the pointer as nullptr, so
that the changes compile and keep working as-is.

The af statistics can be accessed directly from the mapped buffer.
Remove the redundant memcpy, and simplify the call to
afEstimateVariance().

A selection of constants are imported from ChromiumOS.
Move these out of the header, and simplify their documentation. Further
more, add a direct reference to the location they were obtained from.

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).
