nvmap: Implement nvmap_page_mapcount()

Browse Source 
Upstream commit cdd9a571b7d8 ("fs/proc: move page_mapcount() to
fs/proc/internal.h") made page_mapcount() an internal function for Linux
v6.11. This function is used by the NVMAP driver and so implement this
function in the NVMAP driver directly instead. Note that newer kernels
implement folio_entire_mapcount() for compound page counts where as
older kernels use compound_mapcount(). Use conftest to detect which of
these functions is present in the kernel.
