Avoid crashes in very large buffers with long lines

* src/xdisp.c (get_large_narrowing_begv, get_large_narrowing_zv)
(get_medium_narrowing_begv, get_medium_narrowing_zv): Use
'ptrdiff_t' instead of 'int', to prevent integer overflow in
large buffers.  (Bug#72497)

(cherry picked from commit f1e37ae423f3be6224f88a21f30ed40e73a4ce22)
