story(sbb-compact-paginator): variant implementation

[jeripeierSBB]

Depends on #2756

We like to implement the compact variant of the paginator which will be used for little space situations, or e.g. carousel..

Figma: https://www.figma.com/file/9r6xSfNmEfCFxl1yFYedrj/Lyne-Components?type=design&node-id=33767%3A8995&mode=design&t=UPHfQU4257pNfPgG-1

Design Spec:

Tech Spec:

• Should be called sbb-compact-paginator and be placed in the paginator module.
• Should inherit paginator, or a paginator base class or mixin (share common logic).
• The displayed numbers mean page X of Y (X | Y).
• For accessibility reasons the two numbers should be described with aria labels.
• Move the current paginator into a subfolder of paginator and create compatc-paginator entry point and folder (src/elements/paginator/paginator/ and src/elements/paginator/compact-paginator/)
