feat(tracing): Propagate sample_rand to transaction's baggage

[szokeasaurusrex]

continue_trace now propagates incoming sample_rand values to the transaction's baggage. Also, in the case where sample_rand is missing from the incoming trace and needs to be backfilled, this change introduces a mechanism for the backfilled value from the scope's propagation context to be propagated to the transaction's baggage.

The transaction still does not use the sample_rand for making sampling decisions; this PR only enables propagation. A future PR will add support for reading the incoming/backfilled sample_rand and for using this value to make sampling decisions.

Depends on:

• feat(tracing): Backfill missing sample_rand on PropagationContext #4038

Ref #3998
