Use Mirror in Swift (reflection) to load tokens to display in design system toolbox

[pylapp]

Context

We display in the design toolbox the semantic tokens in list.
These values are hard-coded: for example in case of colors semantic tokens a NamedColor enumeration is defined listing all expected tokens which are retrieved then through the themes.
This solution is a bit heavy because we need to list manually the tokens.
In addition some of them can be missing.

Solution

• Study how we can use reflexion on tokens providers
