feat(ui): add a Speed Dial button
Description
These changes add a Speed Dial button, which is a button which displays a list of other buttons when clicked with an animation. The actual "buttons" can be any kind of QWidget, typically QPushButton, but it can also be more exotic widgets such as QOpenGLWidget.
It also adds SIconSpeedDial, which is a service which allows to create a Speed Dial with a list of actions. It is the most simple and typical use case of the Speed Dial and can serve as a reference.
Closes #1093 (closed)
