[glib: 19/30] gatomicarray: Drop volatile qualifier from GAtomicArray API

    gatomicarray: Drop volatile qualifier from GAtomicArray API
    
    This is an API break, but it should not affect third party code since
    that code should not be interacting with the `data` member in a way that
    invokes its `volatile` qualifier (such as copying to an intermediate
    variable).
