cc: Add four new histograms for gpu image decode/upload usage tracking.

This patch adds the following new histograms:
Renderer4.GpuImageDecodeState
=============================
This records the state of the software decode used for gpu upload.
Specifically, it identifies whether the decode was used or not used and
whether it was used/wasted once or several times. The possible states
are all combinations of those values:
- Used, once
- Wasted, once
- Used, relocked
- Wasted, relocked

Renderer4.GpuImageDecodeState.FirstLockWasted
=============================================
This indicates whether the first lock of the decode described above was
used. This is important, since if we waste the first decode, we lose
the guarantee that we can relock and upload this without doing more work

Renderer4.GpuImageUploadState.Used
==================================
This indicates whether the uploaded image was used in raster.

Renderer4.GpuImageUploadState.FirstRefWasted
============================================
This indicates whether the uploaded image was used during the first
ref. In other words, if the ref reached 0 for the first time without
the image being used, this would record "true, it was wasted".
