Reject INT32_MIN in Swift BackForwardList

Reviewed by Geoffrey Garen.
Swift counterpart of 314581@main (a6cd3ca) for WebBackForwardList.swift.
That change rejected INT32_MIN in the BackForwardItemAtIndexForWebContent IPC
handler and reworked itemAtDeltaFromCurrentIndex to range-check without negating
the delta in signed arithmetic.
This ports those changes to the Swift implementation.
This is the first time a Swift IPC handler has taken both a connection and a
completion handler argument, so it requires fixing an omission in the IPC
dispatch code for this combination.
