[mutter] kms/impl-device: Make property ID lookup also handle parsing

[Marge Bot <marge-bot src gnome org>]

commit 1b3e8b4a277311ea05bc83adafccd8b253ba9f83

    kms/impl-device: Make property ID lookup also handle parsing
    
    Values may need to be processed and parsed in custom ways; make this
    possible via the property table infrastructure using a callback.
    Will be used for e.g. parsing rotation and formats.
