cmake: Enable SMB for Windows builds

- Define USE_WIN32_CRYPTO by default. This enables SMB.

- Show whether SMB is enabled in the "Enabled features" output.

- Fix mingw compiler warning for call to CryptHashData by casting away
  const param. mingw CryptHashData prototype is wrong.

Closes https://github.com/curl/curl/pull/4717
