utils: codegen: gen-controls.py: Convert to jinja2 templates

Browse source 
Jinja2 templates help separate the logic related to the template from
the generation of the data. The python code becomes much clearer as a
result.

As an added bonus, we can use a single template file for both controls
and properties.
