Use polymorphic IOSBridge to perform iOS target listing

Summary:
Bulding on the work from prior diffs we can use the created bridge directly. No need to have if statements calling out to sub-functions, just use the base type itself which will use the appropriate implementation.

There's no behavioural change here. Either idb was queried for sims/devices or simctl was queried for just sims, they were always mutually exclusive.
