improve Cocotb integration

• compile and use Xilinx glbl
• handle DesyRDL-generated Python files
• make the Python venv from make env optional for DesyRDL
• add pyUVM RAL generation through DesyRDL

Making the venv optional also when using DesyRDL is intended to give the user some flexibility. Cocotb is currently not part of the basic venv from make env, and when the user installs it in a user-wide venv using pipx, these two venvs seem to confuse each other.

Unfortunately this does not really solve it yet, partly because of https://github.com/cocotb/cocotb/issues/4091 (I forgot the details by now, sorry!)

Maybe with cocotb-2.0 it will be easier because https://github.com/cocotb/cocotb/pull/4293 was merged?

What is currently working well is make env_dev to also install cocotb into the venv.

Currently we can install cocotb in fwk .venv by calling make env_dev. This is temporary solution which works for development. We need better solution for CI/automation.

Thanks, I will update the documentation page here accordingly.

In the meantime, what about the changes in this merge request - are they good for merging? Any comments?

I updated the note in the documentation page a bit.

A work-in-progress state of using cocotb and pyUVM is here: https://gitlab.desy.de/fpgafw/projects/verif/verif_axi4_stream_packetizer

Please consider merging these changes or provide feedback what needs to be improved. I don't have much time left here I'm afraid.
