  tolower: refine the tolower code to avoid a memory access

This improves the performance of this function and the ones that rely on it
(ossl_lh_strcasehash primarily).

    M crypto/o_str.c
    M include/internal/cryptlib.h
    M providers/fips/fipsprov.c

  Log Message:
  -----------
  strcasecmp: implement strcasecmp and strncasecmp

Rather than relying on the locale code working, instead implement these
functions directly.

Fixes #18322
