This change completes the necessary API changes for import assertions discussed in https://docs.google.com/document/d/1yuXgNHSbTAPubT1Mg0JXp5uTrfirkvO1g5cHHCe-LmY. The old ResolveCallback is deprecated and replaced with a ResolveModuleCallback that includes import assertions. Until ResolveCallback is removed, InstantiateModule and associated functions are modified to accept both types of callback, using the new one if it was supplied and the old one otherwise. An alternative that I chose not to go with would be to just duplicate InstantiateModule and associated functions for both callback types. SyntheticModule::PrepareInstantiate's callback parameter was unused so I removed it.
