[SYSTEMDS-3375] CUDA 11.x / CUDNN 8.x support

[corepointer]

This changeset brings CUDA11 and CUDNN8 support to SystemDS. All required API changes to successfully compile & run have been applied. A few library functions are still on the ToDo list. They continue to work under a deprecation notice for the time being.
Tested on CUDA 11.6.1 and CUDNN 8.4

Can you please execute the GPUFullReuseTest and GPULineageCacheEvictionTest tests under the Lineage package as well with the updated CUDA version? You need to uncomment the code in TestUtils.java:isGPUAvailable() to trigger lineage-based reuse in GPU. @corepointer

mvn -q -B test -D maven.test.skip=false -D automatedtestbase.outputbuffering=false -Dtest=org.apache.sysds.test.functions.lineage.GPULineageCacheEvictionTest 2>&1 | tee output-GPULineageCacheEvictionTest.txt worked just fine.
