crt: Use (void*) casts to silence warnings about function pointer casts
Modern GCC and Clang warn for these casts, with warnings like these:
../secapi/_chsize_s.c:20:6: warning: cast from 'FARPROC' (aka 'long long (*)()') to 'errno_t ((*))(int, long long) __attribute__((cdecl))' (aka 'int (*)(int, lo
ng long)') converts to incompatible function type [-Wcast-function-type-mismatch]
20 | f = (errno_t __cdecl (*)(int, long long))
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
21 | GetProcAddress (__mingw_get_msvcrt_handle (), "_chsize_s");
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
By casting to (void*) instead, we can let the compiler do the second
cast to the target function type implicitly, and also silencing these
warnings.
