patch 9.1.1257: Mixing vim_strsize() with mb_ptr2cells() in pum_redraw()

Problem: Mixing vim_strsize() with mb_ptr2cells() in pum_redraw().
Solution: Change vim_strsize() to mb_string2cells() (zeertzjq).

Since vim_strsize() uses ptr2cells() for the cell width of each char, it
is strange to mix it with mb_ptr2cells(), which is used both just below
and in pum_screen_puts_with_attr(), and screen_puts_len() also uses
something similar. Meanwhile mb_string2cells() uses mb_ptr2cells() for
the cell width of each char.

Note that the vim_strsize() and mb_string2cells() actually return the
same value here, as the transstr() above makes sure the string only
contains printable chars, and ptr2cells() and mb_ptr2cells() only return
different values for unprintable chars.

closes: #17003
