ipa: ipu3: Move the AWB stats structures

Browse source 
The structure Ipu3AwbCell describes the AWB stats layout on the kernel
side. We will need it to be used by the AGC algorithm to be introduced
later, so let's make it visible from ipa::ipu3::algorithms and not only
for the AWB class.

The IspStatsRegion will be needed by AGC too, so let's move it in the
same namespace too.
