Subject: ipa: raspberrypi: Use the generic statistics structure in the
 algorithms

Repurpose the StatisticsPtr type from being a shared_ptr<bcm2835_isp_stats> to
shared_ptr<RPiController::Statistics>. This removes any hardware specific header
files and structures from the algorithms source code.

Add a new function in the Raspberry Pi IPA to populate the generic statistics
structure from the values provided by the hardware in the bcm2835_isp_stats
structure.

Update the Lux, AWB, AGC, ALSC, Contrast, and Focus algorithms to use the
generic statistics structure appropriately in their calculations. Additionally,
remove references to any hardware specific headers and defines in these source
files.
