Reporting: Process Report-To headers in HTTPNetworkTransaction

Piece by piece, we are moving the Reporting and NEL processing code from
URLRequest and friends into HTTPNetworkTransaction, to make sure that we
produce reports for network requests as defined by the spec (e.g., for
redirects and cached responses).

This patch moves the processing of the Report-To configuration header.
