Prevent buffer overflow in line-numbering code

* src/xdisp.c (maybe_produce_line_number): Limit the value of
'display-line-numbers-width' to what can be shown in the window,
and set dimension of the lnum_buf[] accordingly.  (Bug#75969)

(cherry picked from commit 0f768b8843bcdbbfa1c64aeee64d2de7d62c0d13)
