Introduces a helper function within tvix-tracing that returns a reqwest
tracing middleware that will ingest the traceparent if otlp is enabled.
It is feature flagged in tvix-tracing so not every consumer of that
library automatically has reqwest in its dependencies.
Tested using netcat to verify that the `traceparent` header is there if
otlp is enabled and missing if otlp feature is disabled.

This introduces another feature flag, "tracy" to the `tvix-tracing` crate.
If enabled (not enabled by default), it'll add an additional layer
emitting packets in a format that https://github.com/wolfpld/tracy can
display.
I had to be a bit tricky with the combinatorial complexity when adding
this, but the resulting code still seems manageable.

Introduce a new common crate that contains tracing boilerplate which then
can be used in the cli, tvix-store and tvix-build crates.
It has otlp as an optional feature, which is currently only used by
tvix-store.
