Extract paginable from the <nuxeo-data-table> to the behavior

During several discussions with Gabriel Barata around ELEMENTS-1257, we've identified that the use of the paginable property (between <nuxeo-data-table> and <nuxeo-page-provider-display-behavior>) could use a rework.
Currently, <nuxeo-data-table> exposes the paginable property, but in <nuxeo-page-provider-display-behavior> there's a blatant check for this property, which ends up not really making sense when the behavior is used in the context of elements other than the <nuxeo-data-table>.
The goal here would be to extract this property (and all of its associated logic) to the behavior, so that we could make it generic enough to be used in other contexts.
