Update recipes for Enhanced Compatibility

[ajschmidt8]

This PR tweaks the changes from #893 and #909 so that rmm produces two packages (has_cma and no_cma) instead of librmm.

Variables specified in conda_build_config.yaml (like cudaMallocAsync) can be used as environment variables, which may simplify things here

Thanks @jakirkham! Testing your suggestions locally real quick and then I will commit them.

[ajschmidt8]

Requires more changes. Switching to draft to prevent accidental merges until then.

[ajschmidt8]

rerun tests

Is the cudaMallocAsync bit still needed here given the changes above and the fact it is implicit based on CUDA version?

[ajschmidt8]

We have some logic below that depends on this extra metadata in the build string. If you know a way we can work around that, then we could remove the extra {{ cudaMallocAsync }} bit here.
