Migrate scripts to LiteX main repository

[mateusz-holenko]

Since those scripts are very closely related to LiteX we should keep them in the upstream repository to make them:

• easier to verify against changes,
• discoverable by new users.

We already moved two out of three scripts upstream, the only one left is https://github.com/litex-hub/litex-renode/blob/master/generate-mocserver-json.py. @CarlFK is it still relevant for you? Do you want it to become a part of LiteX?

@CarlFK: What is the status of the generate-mocserver-json.py script - would you like it to be transferred to the LiteX repo?

[CarlFK]

yes, I think it would be good if it lived upstream. I just reviewed it, looks good to go.

It's purpose is to get a process started that has circular dependencies: Front end js dev doesn't want to write code where this is no back end, and back end fpga dev doesn't want to write code if there isn't anyone working on the front end. generate-mocserver-json.py provides the back end so some js can be written.

So the plan is the front end dev gets started and as soon as something looks promising generate-mocserver-json.py will be implemented in fpga. I was driving this for the hdmi2usb project, but covid has kinda put that need on hold, thus my involvement is stalled. But the plan was for this to be a generic debugging too for any project, thus it should live here and I'm happy to help with it.

For the record - created a PR to litex upstream enjoy-digital/litex#1071.
