Tagging presets: Align text behind icons and center icons

[skyper]

What steps will reproduce the problem?

1. Have a preset with icons in front of keys or within <list_entry />

What is the expected result?

Icons are centered and the text behind the icons is aligned plus empty space is added for missing items

What happens instead?

Except of preset menu, no empty space for missing icons and the text is not aligned
Even in preset menu the icons are not centered

Please provide any additional information below. Attach a screenshot if possible.

So the syntax for menu has to be used for all places where icons plus text is listed below each other and additionally all icons should be centered.

Similar problem exists in preferences: #21208
