[Origin Trials] Rename confusing 'global' variable

The name of variable was causing no end of confusion about when it should be
passed into the various install* methods for origin trials, and when a dummy
object should be passed instead. Renamed to the more sensible 'instanceObject',
as a counterpart to 'interfaceObject' and 'prototypeObject', and now only
instantiate it when necessary (in Window and WorkerGlobalScope blocks).
