Switch to System32 d3d11 and nvapi64 dlls.

This is experimental for watch dogs, where we want to be the system version of d3d11.dll and nvapi64.dll.
This change looks for "original_d3d11.dll" and "original_nvapi64.dll" to pass through.

Works, but is scary to take over d3d11 for the whole machine.
Add a few WatchDogs shaders that are interesting.

These are not part of the fixed folder, that is Mike's playground.  These are here for reference and some small info found during experimentation.

At least one of these has a bad Decompile where it silently truncates the code.
