* feat(label): added animation style property to apply it to circular scrolling animation of label widget

Added an animation style property to be used as animation template for different use cases in different widgets.
This commit implements using this property to set the start and repeat delay of the circular scrolling animation of the label widget.

Closes #3097

* fix(label): changed animation style property's var_type to `const lv_anim_t *`

* example(label): added example showing how to customize circular scrolling animation

* chore(label): ran code-format.py and added missing function prototype to lv_example_widgets.h
