Docs: Modify tables in Supported APIs section

[Garra1980]

System information

• OS Platform and Distribution (e.g., Linux Ubuntu 16.04):
• Modin version (modin.__version__):
• Python version:
• Code we can use to reproduce:

Describe the problem

We should extend tables that track Supported APIs (eg https://modin.readthedocs.io/en/stable/supported_apis/dataframe_supported.html) with different engines - Ray, Dask and Omnisci. This particular task is only about table structure not content (which will be handled separately)

We may create some format for modin functions' doctstrings (specifying whether function is supported or not for different engines) and accordingly generate info in csv tables that will be inserted into Supported APIs sections
