[cogl/wip/cogl-sharp: 21/42] cogl-sharp: Expose CoglPixelFormat

[Damien Lespiau <dlespiau src gnome org>]

commit aef67eb33bf19377124c3efa22e3df020c0ad36f
Author: Damien Lespiau <damien lespiau intel com>

    cogl-sharp: Expose CoglPixelFormat
    
    And thus also enable the generation of yet another method of
    FrameBuffer.
    
    This also introduces a way to tell the generator you want the enum
    members to bo upper case (by default it will generate capitalized enum
    values).
