Listen to Span creation from native layer

[bruno-garcia]

The native SDKs could have a span creation callback that would be leverage by hybrid SDKs such as RN.
In the event of span/transaction creation, the hybrid layer would listen and append to any current transaction under a native operation.

In a way that all spans created in the native layer would be children of this one span.

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!

A workaround would be to continue a transaction from the Native layer, See example.

A workaround is possible getsentry/sentry-dart#721 (comment)
This is a Dart code snippet but I believe you can do something similar with the RN/JS SDK.
