Joseph Huber 06adac8c4e [Libomptarget] Configure the RPC port count from the plugin ...

This patch allows us to configure the port count to what the specific
card would desire for parallelism. For AMDGPU we need to use the maximum
number of hardware parallelism to avoid deadlocks. For NVPTX we don't
have this problem due to the friendlier scheduler, so we use the number
of warps active on an SM times the number of SMs as a good guess.

Note that the max ports currently is going to be smaller than these
numbers. That will be improved in the future.
