feat(span-first): Support before_send_span

[sentrivana]

Description

Add support for before_send_span in span streaming mode.

before_send_span is different from before_send_metric and before_send_log in that:

• it doesn't allow users to drop a span (i.e., return None)
• it only allows to modify specific parts of the span (name and attributes)

To that end, we're exposing a copy of the span in the callback instead of the real thing. Alternatively, we could just expose a simplified dictionary snapshot of the span ({"name": "name", "attributes": {}}), but that'd then bypass any extra logic we have in the span public API (like set_attribute(), which currently stringifies values if not serializable).

See https://develop.sentry.dev/sdk/telemetry/spans/scrubbing-data/ for spec.

TODO

• Looks like we have some unserializable stuff on spans. Need to figure out what it is and why it's there. If we can't get rid of it it might need a stripped down version of the span or a snapshot after all

Issues

• resolves: Add before_send_span #5388
• resolves: https://linear.app/getsentry/issue/PY-2057/add-before-send-span
