This is based on the initial CMake patch by
Arne Schwabe, but extends that to provide
a complete replacement for existing MinGW
build (autotools based) and MSVC build
(openvpn.sln).

The following features are added while switching
these builds to CMake:
 - vcpkg support for MinGW build, allowing for
   trivial cross-compilation on Linux
 - Add unittests to MSVC build
 - Rework MSVC config header generation, removing
   need for separate headers between autotools
   and MSVC

The following advantages are reasons for switching
to CMake over the existing MSVC build:
 - Easier to maintain CMake files without IDE
   than the sln and vcxproj files
 - Able to maintain MSVC and MinGW build side-by-side

The plan is to completely remove the existing MSVC
build system but leave the existing autotools builds
in place as-is, including MinGW support.

CMake is not the intended build system for Unix-like
platforms and there are no current plans to switch
to it.

v2:
 - Reduce default warning level for MSVC to /W2. With
   /W3 the build is just much too noisy, making it
   difficult to spot new warnings.
 - Change MSVC CMake presets to have hardcoded build
   type. When using pkg_search_module MSVC Multi-Config
   builds do not work correctly at all since PkgConfig
   doesn't seem to be able to create multi-config
   libraries like find_package does.
 - Change minGW presets to be Multi-Config capable.
 - Remove OPENVPN_VERSION_MAJOR, OPENVPN_VERSION_MINOR,
   OPENVPN_VERSION_PATCH from config.h.cmake.in.
   They are not required and cause macro redefinition
   warnings in MSVC (with openvpn-plugin.h). gcc doesn't
   warn about this because the definitions are identical
   so no need to fix this in autoheader config.h.in.
