Stopped synthesizing a backing instance variable for the `isTokenAutoRefreshEnabled` property in `FIRAppCheckSettings` because it is unused, resulting in a warning when "-Wunused-property-ivar" is enabled. This resolves the error "FIRAppCheckSettings.m:92:1: error: ivar '_isTokenAutoRefreshEnabled' which backs the property is not referenced in this property's accessor [-Werror,-Wunused-property-ivar]" when building in google3 (where this warning is treated as an error).
