[libdazzle: 1/2] Add libdazzle-1.0 pkg-config package to gir XML file.

[Christian Hergert <chergert src gnome org>]

    Add libdazzle-1.0 pkg-config package to gir XML file.
    
    This ensures that languages that generate compile time bindings can
    obtain appropriate compilations and linking flags from pkg-config.
    
    export_packages option in meson gnome.generate_gir translates into
    --pkg-export=libdazzle-1.0 for g-ir-scanner, which in turn translates
    into one additional line in Dazzle-1.0.gir file:
    
    ```
      <package name="libdazzle-1.0"/>
    ```
