[Perf] Delete unused WebRTC stats metric

[Perf] Delete unused WebRTC stats metric

This CL deletes the old, now-unused version of the WebRTC stats metric. This
metric has long since been ported to TBMv2, and this version uses a library
from Catapult that has been moved, so it is blocking the deletion of a shim.

Ned, please take a look. After this CL lands in Chromium,
https://codereview.chromium.org/2956443002 will remove the shim on the Catapult
side.
