Add UMA stats for amount of memory used by 2D canvas bitmaps

Project Member Reported by chrishtr@chromium.org, Jun 13 2017 
1. Amount of memory used by 2D canvas bitmaps
2. Percent of total renderer memory used by #1
3. Breakdown of #2 and #1 by foreground and background tabs

These statistics will help to inform how much of a memory problem there is in
the need to pin these bitmaps to memory, even for backgrounded tabs.

There should separate stats for RAM vs GPU memory.
There also need to be a break down of where the memory is being held (ex: backing store, compositor, recyclable resource pool) 
Any ideas when this measurement should be taken? at each paint perhaps? do we report this only on pages with canvases?

Eric reports that the GPU process computes its total-memory UMA every 30
seconds on a timer. Perhaps match that?

Only on canvas pages might be ok.

FYI the one for total GPU memory is GPU.ContextMemory.GLES.Periodic
