Ensure streamed span names have low-cardinality span names #22350
Description
For v11, streamed span names should become low-cardinality. Since we'll still support transactions as a fallback, we'll need to check for traceLifecycle and assign different span names for stream or static mode.
Span name rules are defined here: https://getsentry.github.io/sentry-conventions/names/
This is a large(r) task but should be splittable so that we can tackle it in parallel
lower prio but to address:
- function spans
- ui/component spans
