Update SDK to p27 and add CAP-71 auth delegation support. (#1896)

### What

Update SDK to p27 and add CAP-71 auth delegation support.

### Why

Adapting to p27 changes.

### Known limitations

I haven't added targeted tests for CAP-71 functions, as these are just
simple wrappers over host functions. I think a full-fledged example in
soroban-examples would be more appropriate.
