Revert of Drop frames until specified bitrate is achieved. (patchset #12 id:240001 of https://codereview.webrtc.org/2630333002/ )

Reason for revert:
due to failures on perf tests (not on perf stats, but fails running due to dcheck failures), see e.g., https://build.chromium.org/p/client.webrtc.perf/builders/Android32%20Tests%20(K%20Nexus5)

A revert of this CL (patchset #1 id:1) has been created in
https://codereview.webrtc.org/2675223002/ by kthelgason@webrtc.org.

The reason for reverting is: Perf test broke as it made assumptions that quality
scaling was turned off. This turns out not to be the case. Fixed by turning
quality scaling off for the tests..
