For Draw (non-native) and CA modes, we include the per-tile
valid rect in the clip rect from the surface.
For DC (non-virtual) mode, a per-tile clip rect is set on the
visual for each tile, separate from the overall clip rect that
is set on the surface visual.
For DC (virtual) mode, the Trim API is used to remove pixels
in the virtual tile area that are outside the valid / clipped
region.
Note: Although the valid rect is now applied in the native
compositors, it's currently only based on the overall picture
cache bounding rect. Thus, with this patch there isn't any
noticeable performance improvement. Once this lands and is
working correctly, the follow up patch to calculate a smaller
valid region per-tile is a small amount of work.

Adds an #ifdef to the DCLayerTree implementation that allows
selecting whether to use the virtual surface API (enabled by
default) or the regular DC surface API.
For now, this is a compile-time switch. As a follow up to this,
we will support both options at runtime (for example, using the
regular surface API for surfaces that have holes or translucency).

This will allow use of the DirectComposition virtual surface API. If
it turns out that some pages recreate surfaces a lot due to opacity
changing, we can add some extra logic to avoid recreating surfaces
as often, and making use of per-tile opacity in some cases.

This patch include two performance improvements:
- Only rebuild the DC visual tree if different from last frame.
- Use EGLImage instead of pbuffer for DC <-> GL interop.
These fix most of the talos regressions with DC enabled in WR.
