Provide a protocol for GPBExtensionRegistry's lookup support.

This allows some to use an alternative registry if they have a different
implementation.

This is really just wiring though the change to use the GPBExtensionRegistry
protocol vs the concrete GPBExtensionRegistry through the other apis.
