util/xmlconfig: Use a non-xml-string encoding of driver options for Android.
    
    On Android, we don't have user-defined drircs to parse, or even the
    Mesa-defined drirc.  We don't need the option descriptions, or the ranges
    for values, either.  Just "this driver has an option of this name and type
    and this default value" so that the rest of Mesa internals can interact
    with driconf options like normal.  Nothing outside of mesa on android uses
    the entrypoints to get the XML.
    
    AOSP really doesn't want to carry around a 150k XML parsing library for an
    actually unused feature.
    
    We can drop that dependency by making a trivial string encoding (so we can
    reuse the rest of the Mesa plumbing) that we parse directly to values at
    screen init time.
