Remove MobileOptimizerType and all rewrite flags from torch.X and torch._C.X to clean up torch.X and torch._C.X namespaces

The affected rewrite flags are
- CONV_BN_FUSION
- FUSE_ADD_RELU
- HOIST_CONV_PACKED_PARAMS
- INSERT_FOLD_PREPACK_OPS
- REMOVE_DROPOUT
- VULKAN_AUTOMATIC_GPU_TRANSFER

Bc-Breaking Change:

Before this change, the rewrite flags were accessible through all of
1. torch.utils.mobile_optimizer.MobileOptimizerType.X
2. torch._C.MobileOptimizerType.X
3. torch.X
4. torch.MobileOptimizerType.X
5. torch._C.X

But after this change, only torch.utils.mobile_optimizer.MobileOptimizerType.X  (option 1 above) and the newly added torch._C._MobileOptimizerType.X remain
