coreplex: make HasTiles more generic
...
HasTiles now deals with only extremely general tile IOs.
Some RocketTiles specific behavior moved into RocketCoreplex.
BaseTile now has optional LocalInterruptNode.

diplomacy: remove the :=? operator in favour of magic :*=* ( #1139 )
...
The reason for the :=? operator was for when you have an adapter chain
whose direction of cardinality you could not know. We used explicit
directives to tell these compositions which way to go.
Unfortunately, that makes the API leaky. You think the chain of adapters
is just one adapter, but you have to use strange Cardinality scopes to
use it. That's just bad.
The new :*=* just automagically figures it out from the graph.

tile: put a BasicBusBlocker inside RocketTile ( #1115 )
...
...instead of on the master side of the system bus.
People inheriting from HasTileMasterPort might need to add
`masterNode := tileBus.node` to their Tile child class.
