feat(v8): Remove data from SentrySpan & rename types (#11303)

This removes `data` from the span (there is only `attributes` left).
Also, for clarity, I renamed `SpanContext` to `SentrySpanArguments`, and
`TransactionContext` to `TransactionArguments`, as "Context" is heavily
overloaded and IMHO this is confusing today.
