	The SharedItemPool was migrated from Chrome OS to maintain RGBS and AF grids in IPAIPU3Stats. The orginal reason is to reserve the validness unitl the grids are processed in a different thread. However, it leads to a subtle bug which recycles the buffer before sending into AIQ libraries. Since the IPU3 IPA (Unlike Chrome OS) process IPAIPU3Stats in a single thread, It would be simpler to maintain the grids as the members of IPAIPU3Stats, and remove the usage of SharedItemPool.

2021-06-28	stats: Create IPAIPU3Stats and import intel_skycam_statistics_convert()	Umang Jain
	This is will be used to convert statistics received from kernel to AIQ stats format. Specific 3a conversion functions will be added in IPAIP3Stats in subsequent commits. ipu3_stats_get_3a() will extract, memcpy each of 3A relevant structures. It's is intended just before setting the stats for next frame in AIQ::setStatistics(). It receives ipu3_uapi_stats_3a struct from the kernel. This API will be developed per parameter of ipu3_uapi_stats_3a struct in subsequent commit. IPAIPU3Stats will be responsible to take in the AIQ algorithms results set and hardware statistics as input and generate(and convert) AIQ consumable ia_aiq_statistics_input_param structure.
