Closes #22927

When using the trace profile lifecycle in @sentry/profiling-node, trace lifecycle profiling was set up without checking the session sampling decision. As a result, chunk profiling would start on span start even when profileSessionSampleRate resulted in an unsampled session.

This change skips trace lifecycle profiling setup when the session is not sampled, ensuring that profileSessionSampleRate is respected in the trace lifecycle as well.

A regression test was added for profileSessionSampleRate: 0 with the trace profile lifecycle.
