feat(button): add icon alone UIKit VitaminButton type, and refactor icon management

daniel-dumortier commented 2 years ago

Changes description

I added the ability to define a 'icon Alone' version of VitaminButton. I also reworked the way to specify which type of icon you want (for already existing trailing and leading icons) And I took advantage of this PR to change icon size on large and medium button (see #74)

Context

This PR solves #52
It also solves #74

Other information

I am not sure it is Vitamin compliant, but I reworked the code to give the ability to have different icons for different states (that was allowed before by the previous code, but did not work well)
