feat(spans): Add topic definition for buffered-segment topic

[shruthilayaj]

We're building a new pipeline to support performance issues with span streaming,
at a high level, it looks like this

the buffered-segments topic will expect to receive a list of spans. As of this
moment, these spans will have the exact same schema as ones we consume
from the snuba-spans kafka topic, the SpanEvent definition is just copied from
the snuba-span schema. we might deserialize the spans to drop fields before pushing to redis
as a memory optimization at which point the span schemas will diverge.

The following repositories use one of the schemas you are editing. It is recommended to roll out schema changes in small PRs, meaning that if those used versions lag behind the latest, it is probably best to update those services before rolling out your change.

✅ This PR should be safe to roll out to consumers first. Make sure to bump
the library in the following repos first:

getsentry/sentry

...then in the other repos:

getsentry/sentry

Take a look at the README for how to release a new version of sentry-kafka-schemas.
