APM: Change 3 UMA metrics to fewer but linearly distributed buckets

APM: Change 3 UMA metrics to fewer but linearly distributed buckets

In this change WebRTC.Audio.ApmCaptureInputLevel{Average,Peak} are
changed to 64 buckets, while WebRTC.Audio.AgcLevel is changed to 50
buckets. All three are changed to have linear spacing between buckets.

Also, the metrics are renamed to avoid stats conflicts because of different bucket schemes:
- WebRTC.Audio.AgcLevel -> WebRTC.Audio.AgcSetLevel
- WebRTC.Audio.ApmCaptureInputLevelAverage -> WebRTC.Audio.ApmCaptureInputLevelAverageRms
- WebRTC.Audio.ApmCaptureInputLevelPeakRms -> WebRTC.Audio.ApmCaptureInputLevelPeakRms

Is there already a lot of data for these histograms? If so, I'd suggest changing
the names and obsoleting the old ones - you're going to get the data mixed
together from the 2 buckets schemes which makes analysis very ugly.

I don't know, so I changed the names to be on the safe side.
