Muxed address support sketch for Soroban SDK.

This introduces the `MuxedAddress` type that maps to either `AddressObject` or `MuxedAddressObject`.

In order to not 'leak' the muxed addresses everywhere (as they have pretty narrow use cases), introduce a separate token interface that supports muxed addresses for transfer (could also support e.g. transfer_from). This is basically token extension, but a bit clunkier due to the lack of overload support. The amount of copy-paste could be reduced though with some code generation (I'm not sure that's necessary though). Also only expose muxed addresses to generate clients when that's explicitly requested, as again users normally don't need to worry about them.
