46a8c094 - [NFC][analyzer] Conversion to CheckerFamily: RetainCountChecker (#152138)

[NFC][analyzer] Conversion to CheckerFamily: RetainCountChecker (#152138) This commit converts RetainCountChecker to the new checker family framework that was introduced in the commit 6833076a5d9f5719539a24e900037da5a3979289 This commit also performs some minor cleanup around the parts that had to be changed, but lots of technical debt still remains in this old codebase.
