Improve the performance of sending the AmoebaVdwLambda to Cuda using pinned host memory; Updated the AmoebaVdwForceProxy to version 3, and added backward compatibility to version 2; updated TestAPIUnits.py to handle the per particle lambda flag

argument.

of just 1.  Backwards compatibility is provided by making the 2nd force constant
default to -1, which is reinterpreted as "copy the first force constant".

Updates both the reference and CUDA kernels.
