Prepare API generator for automatic check

[Akirathan]

Pull Request Description

First step of #10507. Preparations for the Standard.Base API check job that will be introduced in a follow-up PR. In this PR, the functionality of DocsEmitSignatures is modified and tested such that its generated signatures for a module is ready for usage in the API check job. Most importantly, the signatures are sorted.

Sorting of the generated signatures prevents future false-positive failures of the API check job when somebody just reorders items in a module.

Important Notes

Further modifications to DocsEmitSignatures:

• Every definition in a module is represented as a list item in the Markdown for convenient rendering.
• Synthetic and empty modules are skipped.
• The directory structure of the generated docs/api corresponds to the directory structure in src.
  • Previously, it was docs/api/Standard/Base/Any.md but now it is just docs/api/Any.md (which was generated from src/Any.enso).

Example output is:

Shouldn't we be using org.enso.scala.wrapper modules's convertors anyway?

[JaroslavTulach]

Maybe we could select the directory based on the "type of documentation" - e.g. api for --docs=api and md for --docs or --docs=md

[JaroslavTulach]

Skipping namespace and name from the directory structure? That is probably good idea. CCing @radeusgd
