feat(interactions): Add interactions sample rate to browser tracing integrations

[edwardgou-sentry]

Adds a interactionsSampleRate option to browser tracing integrations to allow users to apply an additional sample rate filter on interaction spans.

interactionsSampleRate is applied on top of the global tracesSampleRate.
Therefore if interactionsSampleRate is 0.5 and tracesSampleRate is 0.1, then the actual sample rate for interactions is 0.05
