Necessary Support for Newer Linux Distros

[kimmeljo]

Description & Motivation

Newer Linux distros complain about installing things globally via pip. This is problematic for hard dependencies of Cosim like cocotb. This PR introduces Python virtual environments into the Cosim flow to make these newer distros happy.

Testing

All testing is theoretical transparent in the existing tests as the change should be fully backwards compatible. But if more explicit testing is desired, it can be added.

Backwards-compatibility

Is this a breaking change that will not be backwards-compatible? If yes, how so?

Not a breaking change. Everything should still work on older systems too. We are just using a Python virtual environment.

Documentation

Does the change require any updates to documentation? If so, where? Are they included?

Not doc updates for now but some might be warranted?

@mkorbel1 do I need to wait for a ROHD release to get these changes? Looks like the cosim repo doesn't override the rohd dependency to point to main.

No, you can just pull main of rohd-cosim which now has the fixes
