Fluid: Initial changes for OpenMP GPU supportfluid-mantaflow-gpu

Contains basic support for OpenMP GPU offloading.
That is, offloading of fluid KERNEL loops to the GPU.

This branch offloads pressure and advection calls only - the 2 most
expensive operation per step. In theory though, any function can be
offloaded.

For now, this branch needs to be build with a compiler that supports
Nvidia GPU offloading. Exact GPU models need to be specified via CMake.
