This allows clien implementors to micromanage the state of the protobuf
`encoder` if they want, or to just let the library handle allocation and
garbage collection of encoder states when that level of resource
managment is not required.
The `tick_common` function is only used once.
Removing the indirection also lets us see that we were calling
`sample_gc_metrics_if_needed` twice in a row on each tick.
in `Opentelemetry_client_cohttp_lwt.with_setup` we should now wait for
the cleanup to be done, by sneaking in a `unit Lwt.u` that is only
resolved after the cleanup is done.

it's cleaner to emit GC events on ticks rather than on GC,
because it avoids both spamming if the GC is very active, and
emitting nothing when there are few allocations.
