Implement an overscan support for tiles, so that adaptive sampling can
rely on the pixels neighbourhood.

Currently was only used for logging, but better to fix the size so
that it matches reality.
The issue was caused by decoupling number of shadow intersections
and using much higher number for CPU. This caused the total state
on GPU to be logged as 10s of gigabytes instead of 100s of megabytes.

* Split GPUDisplay into two classes. PathTraceDisplay to implement the Cycles side,
and DisplayDriver to implement the host application side. The DisplayDriver is now
a fully abstract base class, embedded in the PathTraceDisplay.
* Move copy_pixels_to_texture implementation out of the host side into the Cycles side,
since it can be implemented in terms of the texture buffer mapping.
* Move definition of DeviceGraphicsInteropDestination into display driver header, so
that we do not need to expose private device headers in the public API.
* Add more detailed comments about how the DisplayDriver should be implemented.
The "driver" terminology might not be obvious, but is also used in other renderers.

Noticed while looking into flickering issues in viewport.
Doesn't seem to solve the flicker issue for me, but is something
what is supposed to be happening anyway.

This includes much improved GPU rendering performance, viewport interactivity,
new shadow catcher, revamped sampling settings, subsurface scattering anisotropy,
new GPU volume sampling, improved PMJ sampling pattern, and more.
Some features have also been removed or changed, breaking backwards compatibility.
Including the removal of the OpenCL backend, for which alternatives are under
development.

all the changes since intermediate changes would often fail building or tests.
