More Windows fixes. (#8123)

- The bootstrapped compiler is run from its build directory since we
    need to use during build step (as opposed to after installation like
    everything else).

    On Windows we need the dlls it uses in the same dir since there is no
    RPATH. Luckily the only dll it needs right now is OpenModelicaRuntimeC.

  - Disable autoconf based config genration for source code FMUs on Windows
    This is temporary until I can find a good way.

    Small fix for checking source fmu autoconf config generation. Report
    any errors properly.

  - Do not declare function RDTSC() as inline. Instead it should be static
    (if it needs any qualifier at all)

  - Disable command line compile definition WITH_IPOPT for now. The define
    is already hard coded in omc_config.h. Which means this leads to warnings
    for every compilation unit. Until we remove the hard coded definition
    in omc_config.h disable this one.
