Switch to using cuda-toolkit over cudatoolkit

[mdemoret-nv]

Description

This PR makes the following changes:

• Updates dev_env.yml to install cuda-toolkit over cudatoolkit
• We still have cudatoolkit=11.8 listed at the end. This is necessary to specify which version to use. Some packages still use cudatoolkit and without specifying the version, 11.7 gets installed.
• Updated the conda build meta.yml to match dev_env.yml
• Also made some updates to remove warnings and hidden errors
• Updated the utilities repo to no longer require Cython unless its used
• Allowed us to remove Cython as a dependency in MRC

Checklist

• I am familiar with the Contributing Guidelines.
• New or existing tests cover these changes.
• The documentation is up to date with these changes.

It looks like Morpheus is having issues when we just install cuda-toolkit, vs cudatookit, on some internal dgx machines, either because CMake isn't reliably finding all the installed headers/libraries, or because they're not being installed correctly.

These changes should probably be tested in a completely clean environment to make sure they work outside of dev/ci.

I think its the opposite, we're getting build issues when we install cudatookit, which are resolved by installing cuda-toolkit

My bad, I had it backwards :). Thanks David.

LGTM.
