feat(tvix/tracing): http propagation for axum

Browse source 
It introduces a new accept_trace function for axum0.7 which can be used
to accept a header trace from a received request. This function can be
used for tonic 0.12 once that version is released, and the specific
`accept_trace` function within `tvix_tracing::propagate::tonic` can then
be removed.

This also integrates http propagation into the nar_bridge crate.
