rfnoc: Add post_init() method to noc_block_base

This method allows running a fixed set of rules to check the internal
consistency of a block. This may be necessary, because blocks authors
may incorrectly implement a certain design rule, and we want the ability
to not start an RFNoC graph with blocks that have rule violations which
we can write checks for.
