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

To that end, we're now serializing the span earlier, and exposing the serialized dictionary in the before_send callback. This is consistent with metrics and logs. It also means we're now queuing dictionaries instead of StreamedSpan instances in the span batcher, which should also decrease our memory footprint.

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

Issues
