CMake FMU runtime dependencies for Windows (#9544)

* CMake FMU runtime dependencies for Windows

  - Exclude system libraries for "modelica"
  - On Windwos `DIRECTORIES` has to be used to specify
    directories of dependencies.
  - "all" probably needs to have `DIRECTORIES` with all of
    the Windows systems locations. But that doesn't sound like a
    good idea to run "all" on Windows.
  - Check if FMI_INTERFACE_HEADER_FILES_DIRECTORY has fmi2Functions.h
