Rename webkitdirs::willUseIOS{Device, Simulator}SDKWhenBuilding() to willUseIOS{Device, Simulator}SDK()

Rubber-stamped by Alexey Proskuryakov.

The functions webkitdirs::willUseIOS{Device, Simulator}SDKWhenBuilding() are not specific to building

convey their general-purpose nature of determining whether we are using the iphoneos or iphonesimulator SDK.
