[PATCH v4 04/10] cmake: fall back to using `vcpkg`'s `msgfmt.exe` on Windows

["Johannes Schindelin via GitGitGadget" <gitgitgadget@xxxxxxxxx>]

From: Johannes Schindelin <johannes.schindelin@xxxxxx>

We are already relying on `vcpkg` to manage our dependencies, including
`libiconv`. Let's also use the `msgfmt.exe` from there.
