Add environment checks

[KSGulin]

This PR adds environment checks that will help detect a broken sparsify environment before a run is fully launched. There are three pathways by which environment checks are launched:

• The CLI command sparsify.check_environment will run all health checks
• Running an experiment with sparsify.run training-aware or sparsify.run sparse-transfer will run health checks relevant to these two pathways
• Running an experiment with sparsify.run one-shot will run the health checks relevant to one-shot

Currently implemented health checks
GPU device check - this is a non-failing check, but it will raise a loud error
ORT health check - this is a failing check which will point the user to the ORT-GPU dependency matrix

Test Plan

• sparsify.check_environment
• CUDA_VISIBLE_DEVICES="" sparsify.check_environment
• sparsify.run training-aware --use-case image-classification --model mobilenet-v1 --data /network/datasets/imagenet --optim-level 0
• sparsify.run one-shot --model model.onnx --data coco_calibration --use-case cv-detection --optim-level 0.5
• Test on system with broken ORT-GPU environment

The base branch was changed.
