1. Track the total number of GPU bytes allocated by WebRender. …

   This is useful for sanity-checking memory reports, and we'll also use it
   for our texture eviction heuristic.

2. Switch GpuCache frame_id tracking from device::FrameId to render_back… …

   …end::FrameId.
   
   It should really be using the latter, so that it can avoid hand-rolling
   the frame increments and just use the one already available on
   frame_builder.
   
   In the next patch, we rename the types to make the difference clearer.

3. Rename device::FrameId to device::GpuFrameId. …

   This type identified frames as sequenced by the device layer, whereas
   render_backend::FrameId identifies frames as sequenced by the render
   backend. I'm not sure whether there are known cases where these will
   diverge, but it seems plausible that they might, and so we should more
   clearly distinguish the types.

7. Properly handle entries moving between shared and standalone. …

   We also switch the boolean from 'in_shared_cache' to 'standalone', since the
   latter is a bit shorter.
