Reland "Avoid using `isolated` wrt. AssociatedInterfaces."

This is a reland of c9fe34f2f9f675e4331d731cc813fa8b0adbdf7f, which updates
a new call site of mojo::MakeIsolatedRequest that was introduced after the
the CL went through the CQ try jobs but before the CL landed.

Original change's description:
> Avoid using `isolated` wrt. AssociatedInterfaces.
> 
> The term `isolated` is already widely used for origins. Using it also
> to describe AssociatedInterfacePtrs and AssociatedInterfaceRequests
> that are associated with dedicated or a disconnected message pipe 
> (mostly for testing) is confusing. Instead, use the words `dedicated`
> and `disconnected`, respectively.
