[ObjC ARC] Converts ios/chrome/browser/ui/autofill:autofill to ARC.
Automatically generated ARCMigrate commit
Notable issues:
autofill_client_ios had a variable commented as weak but not actually handled as such. Tried using Weak_NS_Object but it had incorrect behavior wrt autorelease pools. Since the file is only currently included in arc converted targets, __weak was used which functions correctly.
