    meson: Simplified introspection option check
    
    The build of the introspection data depends on the existence of the
    GObject library, the `g-ir-scanner` program, and the build not being
    a cross build.
    
    The check to the GObject library has been removed, because it is
    required for compiling libgit2. The gir variable has also been
    removed because there is no need to store the intermediate state.
    
    Finally, the `build_gir` variable has been renamed to remain
    consistent with other similar variables like `enable_ssh`.
