refactor(corp/tvixbolt): adapt for tvix-eval's upcoming observer API r/4631

Instead of the previous hack which painfully threaded through
a structure that the disassembler could write to, Tvix's evaluator is
gaining a new "Observer" API which lets library clients observe
compilation output (and, soon!, runtime tracing).

This adapts tvixbolt to use this observer interface (with the default
`DisassemblingObserver`) to populate the `bytecode` field of its
output.

This is purely a mechanical change, no functionality is impacted.
