Sub-issue of https://github.com/open-telemetry/opentelemetry-browser/issues/209 Move the @opentelemetry/instrumentation-document-load instrumentation from [opentelemetry-js-contrib](https://github.com/open-telemetry/opentelemetry-js-contrib) We will follow the decisions made in the move of other instrumentations like fetch ([issue](https://github.com/open-telemetry/opentelemetry-browser/issues/259)) - should be part of the instrumentation package - any required util should be moved there - use logs instead of Span events. Integrate with resource-timing instrumentation with the results of the proposal in https://github.com/open-telemetry/opentelemetry-browser/issues/312
