Subject: [PATCH 1/2] Directory.Build.props: set minimum Windows API version

Enforce a minimum Windows API version of build 16299 (aka '1709',
aka 'Redstone 3', aka 'Fall Creators Update'). This was the previous
target SDK version before 240f73ee5 changed the native projects to
use the latest Windows SDK installed.

Setting the TargetPlatformMinVersion property for the native projects
will prevent use of APIs newer that the specified version, with newer
Windows SDKs.

Subject: [PATCH 2/2] Build.bat: loosen Windows SDK checks

Since we now build with the latest installed Windows SDKs (whilst still
enforcing a minimum API compatibility), we can delete this check for a
specific Windows SDK installation.
