And looking at this page, it is said that the minimum version
supported by this function is Windows 2008:
https://docs.microsoft.com/en-us/windows/win32/api/bcrypt/nf-bcrypt-bcryptgenrandom
Now, your changes in MkvcBuild.pm and the backend code assume that
we need to include bcrypt.lib since MSVC 2015 (at least version
14.00 or _MSC_VER >= 1900. Do you have a reference about when this
has been introduced in VS? The MS docs don't seem to hold a hint
about that..
