DAL/Rollups: support request_adal_page in Fueled_PVM

Stacked on top of !15640 (merged)

This MR extends the work done in MR !15640 (merged) to support reveal_adal_page requests in fueled PVM module.

This is done by extending the page_content function to take into account the values of attestation_threshold_percent and restricted_commitments_publishers found in reveal_adal_page's payload (in case of an adjustable DAL request) to decide whether a page (or more exactly; its slot) is attested or not.
