[PATCH v2 04/13] mm/gup: move try_grab_page() to mm/internal.h

[Jason Gunthorpe <jgg@xxxxxxxxxx>]

This is part of the internal function of gup.c and is only non-static so
that the parts of gup.c in the huge_memory.c and hugetlb.c can call it.

Put it in internal.h beside the similarly purposed try_grab_folio()
