Add explicit spans, for async tracing.
...
These spans require the user to pass the surrounding span, if any, when
entering a new span. They use the information inside (which is collector
specific) to track what asynchronous task is currently being executed.
Wrappers around `trace`, specific to an async library (e.g. Eio, lwt,
Async, etc.) can then smooth this over by providing a `with_async_span`
construct that uses some implicit contextual storage to carry the
`surrounding` scope around.

chore: depend on core in trace-tef
...
This changes trace-tef to depend on trace-core instead of trace, to
avoid clashing with the toplevel's Trace module when starting utop.

refactor: avoid the cursed stdlib Trace module by adding trace.core
...
this way, we can actually use only `trace.core` when we also expect to
use compiler-libs.toplevel (which contains a naked `Trace` module, which
would cause .cmi collisions). The library `trace` still exists, and just
forwards to `trace.core`.

perf(trace-tef): improve behavior of collector under contention
...
writers still do one lock+unlock per event, but the collector can read
multiple events at once using Queue.transfer.

even tracy doesn't have that. Otoh a message should have an optional
