Only include breadcrumbs within trace duration

### Problem Statement

Currently, in the breadcrumbs view within the trace waterfall, we appear to include breadcrumbs from the entire user session. This makes searching for breadcrumbs relevant to the trace a cumbersome process as we include a lot of potentially irrelevant data.

### Solution Brainstorm

Filter the breadcrumbs to only include those that occur during the trace duration, or add a filtered option alongside the existing breadcrumbs data.

### Product Area

Unknown

Start by locating the breadcrumbs view within the trace waterfall and inspect how it currently loads session breadcrumbs. Determine whether trace-duration filtering or a separate filtered option fits the existing view; done means breadcrumbs relevant to the trace can be shown without searching the entire user session.
