Replace handler::primary_key_is_clustered() with handler::pk_is_clustering_key()

Browse Source 
This was done to both simplify the code and also to be easier to handle
storage engines that are clustered on some other index than the primary
key.

As pk_is_clustering_key() and is_clustering_key now are using only
index_flags, these where removed from all storage engines.
