av1parser: Fix array sizes in scalability structure

Since the AV1 specification is not explicitly mentioning about
    the array size bounds, array sizes in scalability structure
    should be defined as possible maximum sizes that can have.

Also, this commit removes GST_AV1_MAX_SPATIAL_LAYERS define from
    public header which is API break but the define is misleading
    and this patch is introducing ABI break already
