Improve `FloatingButton` styling.

[MaximAlien]

Description

• Remove shadow that is applied to FloatingButton to be aligned with other stylable views and to improve performance (shadow usage leads to such warning: The layer is using dynamic shadows which are expensive to render. If possible try setting 'shadowPath', or pre-rendering the shadow into an image and putting it under the layer.).

• Add the ability apply type and cornerRadius while creating FloatingButton.
