GHA/windows: add MSVC wolfSSL job with test

Fix the file of wolfssl.c because of this warning/error:
```
curl\lib\vtls\wolfssl.c(1017,42): error C2220: the following warning is treated as an error [curl\bld\lib\libcurl_object.vcxproj]
curl\lib\vtls\wolfssl.c(1017,42): warning C4267: 'function': conversion from 'size_t' to 'unsigned long', possible loss of data [curl\bld\lib\libcurl_object.vcxproj]
```

`size_t` in MSVC is different. Change it to `unsigned long` because
`wolfSSL_ERR_error_string_n` last argument is defined as
`unsigned long`.

Closes #14193
