pow() calculation ouside of the for() loop

Problem: vim_strnchr() is strange and unnecessary (after v9.1.1009)
Solution: Remove vim_strnchr() and use memchr() instead. Also remove a
comment referencing an #if that is no longer present.
vim_strnchr() is strange in several ways:
- It's named like vim_strchr(), but unlike vim_strchr() it doesn't
support finding a multibyte char.
- Its logic is similar to vim_strbyte(), but unlike vim_strbyte() it
uses char instead of char_u.
- It takes a pointer as its size argument, which isn't convenient for
all its callers.
- It allows embedded NULs, unlike other "strn*" functions which stop
when encountering a NUL byte.
In comparison, memchr() also allows embedded NULs, and it converts bytes
in the string to (unsigned char).
