Revert of cc: Replace recorded region with direct map lookup (https://codereview.chromium.org/196343005/)

Reason for revert:
Probably broke telemetry's testMeasurementSmoke (which only runs on the cq and not the main waterfall for some reason): http://crbug.com/350697

Original issue's description:
> cc: Replace recorded region with direct map lookup
> 
> If the viewport is extremely large, then keeping track of the recorded
> region in PicturePile with an actual Region becomes extremely slow due
> to a large number of rects being inserted into it.
> 
> The recorded region behaves as a cache to the picture map; it's a
> simpler way to know the state of all of the recordings contained within.
> 
> In practice, the recorded region is only used for two things: a "should
> this pile bother to create tilings" optimization and a "can a tile be
> rastered in this content rect" check aka CanRaster.
> 
> The optimization for "should create tilings" is replaced by a
> has_any_recordings_ boolean, which could have a false positive in theory
> (resizing to a smaller but non-empty size), but which shouldn't happen
> in practice.  Even if it did, this would only be a performance penalty
> for creating no-op tilings that can't create tiles (due to CanRaster).
> 
> The CanRaster check is replaced by a viewport hint, as most tiles that
> the tiling creates will be inside of the very large expanded viewport
> during recording, turning an expensive Region.Contains check to a
> Rect.Contains one.  In the edge cases where tiles are being created
> outside of that expanded viewport, it will check the picture map
> directly.  This should only happen when the user has scrolled thousands
> of pixels without a commit.
