CloudPG v8 Upgrade

[CodingDepot]

This PR aims to upgrade the CPG-dependency to version 7 while still maintaining the full functionality of the CloudPG. The work done in this PR also includes changes from @oxisto to #58.

This PR is still WIP, necessary steps include:

• [x] Fix compilation errors
• [x] Use new "Name" classes for Nodes
• [x] Update the included RubyLanguage
• [x] Go: Specify a working pass evaluation order so that no Nodes are missing
• [ ] Go: Make sure a valid path from the Label to the goal is formed and all respective tests pass
• [x] Python: Specify a working pass evaluation order so that no Nodes are missing
• [x] Python: Make sure a valid path from the Label to the goal is formed and all respective tests pass

Main problems at the moment seem to be:

• RequestPass.kt (line 53)
• GinGonicPass.kt (line 122)

In both locations, trying to dereference a DeclaredReferenceExpression fails as the "refersTo" field is always null.

Edit: The CryptographyPass (line 36) suffers from the same issue. Interestingly, GoCryptoPass (line 46) does not after adding the GoExtraPass as a dependency.

The problem in the RequestPass (for python requests) can be fixed by making it depend on the GoExtraPass.

This sound strange. I suspect that the general order of passes ist still incorrect. I can try to have a look later.

After a quick look, I would suggest that all of these special passes should depend on at least the VariableUsageResolver and the CallResolver.

We should probably add a new base class that all of those passes derive from and add the annotation to that base class.
