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
