6ff33edc - [alpha.webkit.NoUnretainedMemberChecker] Ignore system-header-defined ivar / property of a forward declared type (#133755)

[alpha.webkit.NoUnretainedMemberChecker] Ignore system-header-defined ivar / property of a forward declared type (#133755) Prior to this PR, we were emitting warnings for Objective-C ivars and properties if the forward declaration of the type appeared first in a non-system header. This PR fixes the checker so tha we'd ignore ivars and properties defined for a forward declared type.
