[glib] Make GChecksum more fully introspectable

    Make GChecksum more fully introspectable
    
    In 2.34, g_compute_checksum_for_bytes() was added, but this patch
    allows binding users to use the incremental update API; this is
    significantly more efficient than reading entire files into memory.
