Use Windows library for cryptographic checksumscng_backend

Add a new feature to libbb, FEATURE_USE_CNG_API, which enables the
use of the Cryptography API: Next Generation library to calculate
checksums.  It is disabled by default except in the mingw64u default
config, as the API requires Windows 10+ to function.  Usage of this
API provides a size benefit and delegates hardware optimizations to
the operating system cryptography library.

Based on GitHub PR #498 by rfl890.

Saves 4064 bytes in the mingw64u case.
