remove opencensus bridge support (#10406)

This removes the configuration of the OpenCensus bridge from the
Collector. This means that any metric still relying on it will no longer
be emitting metrics.

Closes #10414
Closes #8945

This is blocked until
open-telemetry/opentelemetry-collector-contrib#29867
is completed.
