helpers: Add option helpers for types that are either a lua str or a value (#876)

Browse source 
Those types needed the following code in apply:

if builtins.isString value
then mkRaw value
else value

This commit avoids this boilerplate, and clarifies that the `str` is lua
code in the documentation.
