Refactor ISF_Acts packages; support only SimKernelMT for ActsFatras
As we will use Acts-Fatras exclusively for the Inner Detector, only
a single simulator/processor is needed.
We are not supporting SimKernel
algorithms with
Acts-Fatras tools, so ISF_ActsFatrasServices/ActsSimTool
codes were
moved into ISF_ActsFatrasTools/ActsFatrasSimTool
, the latter
becoming a BaseSimulatorTool
that also implements the processing of
particles.
Supporting only SimKernelMT
, ISF_ActsFatrasServices
has been removed
altogether.
Other general clean-up of comments and formatting.
Note comments are retained for future iterations on this work.
