Draft:integrate FCS-GPU to athena
update the FCS-GPU to master and integrate to athena. The GPU kernels are in ISF_FastCaloGpu, and the ISF_FastCaloSimServices is used to make the geometry with GPU EDM and ISF_FastCaloSimEvent is used to copy the inputs to GPU and parallelize the simulation of hits in GPU. WIP: a test with ttbar sample for validation.
