Send span origin

Description

Backlink getsentry/team-sdks#14

### Tasks
- [ ] https://github.com/getsentry/sentry-javascript/issues/8510
- [ ] RN integrations

[krystofwoldrich]

JS SDK needs to be updated too, otherwise, only some integration will record the trace origin.

• Send trace origin team-webplatform-meta#61

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you label it Status: Backlog or Status: In Progress, I will leave it alone ... forever!

@krystofwoldrich with getsentry/sentry-javascript#8510 done, what's missing here?

[krystofwoldrich]

The JS Core Integrations are now sending the trace origin, the RN Integrations are still todo.
