[topgen] Don't copy data from block into instances

There's no need to do this, as long as we can look up the block
quickly. The nicest way to do that would be to add a "block" field to
the instance dictionary, but that would be enormous when we dumped
top_earlgrey.gen.hjson (I tried it - it added 32k lines!), so we just
pass around a dictionary mapping block name to the IpBlock object
instead.

Note that we do still have to copy inter_signal_list, because that
gets annotated (through references; it's not very easy to trace) by
the code in intermodule.py.
