Follow-up to #5882 to fix some issues I saw when building with VS2026.

* Add back the setting for `ReleaseStatic` configuration that I deleted
by accident. (The build error without this says that a the binary needs
an entrypoint. So I'm assuming that without the `ConfigurationType` it
assumes application instead of library.)
* Added a missing include to a header.
* Moved a template definition to be after the definition for a type it
references.
* Suppressed a warning from WIL code.
