Add DeepSpeed easyblock

[VRehnberg]

Adds an EasyBlock for building DeepSpeed. Main reason for not handling it in the easyconfig is to access cuda_compute_capabilities.

Also expands PythonPackage easyblock so that PATH and LD_LIBRARY_PATH is exported for runtest with testinstall as well (compared to only PYTHONPATH originally).
