Added initial CCD library code

Added some basic CCD library functionality
to be able to set Windows displays directly
from the code. This will enable future native
HDR support through windows, as well as
allow positioning and screen setup to work
better through here than via the AMD driver.

Will still need to work on AMD Eyefinity support
once this is completed.
