net: page_pool: scale alloc cache with PAGE_SIZE

The current page_pool alloc-cache size and refill values were chosen to
match the NAPI budget and to leave headroom for XDP_DROP recycling.
These fixed values do not scale well with large pages,
as they significantly increase a given page_pool's memory footprint.

Scale these values to better balance memory footprint across page sizes,
while keeping behavior on 4KB-page systems unchanged.
