Fix MMCV_CUDA_ARGS so it supports multiple arch
Thanks for your contribution and we appreciate it a lot. The following instructions would make your pull request more healthy and more easily get feedback. If you do not understand some items, don't worry, just make the pull request and seek help from maintainers.
Motivation
Currently is not possible to support multiple cuda arches because a space separated string of gencode arguments get passed as a single nvcc argument which triggers a compile error (should be separate arguments).
Modification
Split the MMCV_CUDA_ARGS variable to correctly pass it to the compiler.
BC-breaking (Optional)
Does the modification introduce changes that break the backward-compatibility of the downstream repositories? If so, please describe how it breaks the compatibility and how the downstream projects should modify their code to keep compatibility with this PR.
Use cases (Optional)
If this PR introduces a new feature, it is better to list some use cases here, and update the documentation.
