[Feat]: Implement customisable properties on Layout for "Mobile Navigation"

[adnanqaops]

Describe the solution you'd like

1. Definable width of the navigation display
2. Orientation (left, middle right) of the navigation display (given it is for example 80% of the screen width
3. Definable width in % per navigation entry
4. Auto-Width - based on text on navigation entries (so, longer texts are still full to see and shorter texts would not mean "too wide nav element"
5. Auto Distribution (all elements together fill the configured width of the navigation display
