    igvm: fix build when igvm is not installed in a well known path

    `stubs/igvm.c` includes `igvm-internal.h`, that in turn includes the igvm library.
    This is required just for the QIgvm declaration and creates an
    unnecessary dependency on the library.

    Since igvm is not listed as a dependency of stubs, this results in build
    failing when the library is not installed in a "well known" path of the
    system.

    Add a forward declaration for QIgvm and move the definition of
    `qigvm_directive_madt` to `igvm.h` so that we can drop `igvm-internal.h` from
    `stubs/igvm.c`.

    Fixes: dea1f68a5c ("igvm: Fill MADT IGVM parameter field on x86_64")
