Revert "Structured ICE logging via RtcEventLog."

This reverts commit eed5aa8904d09179971d3f4e7e10c109d7c62bfc.

Reason for revert: breaks downstream projects.

Original change's description:
> Structured ICE logging via RtcEventLog.
> 
> This change list contains the structured logging module for ICE using
> the RtcEventLog infrastructure, and also extension to the log parser and
> analyzer.
