internal/trace: add a wrapper for tracing

This package adds a StartSpan function that does nothing unless an
implementation for the StartSpan function is injected in. That allows
us to have the frontend and worker mains inject the implementation
while internal/fetch and internal/source can use the StartSpan
function without depending on opencensus's tracing library.

For golang/go#61399
