Devnet sync events (#7911)
This request implements an end to end Polygon state sync in the devnet.

It does this by deploying smart contracts ont the L2 & L2 chain which
follow the polygon fx portal model with security checks removed to
simplify the code. The sync events generated are routed through a local
mock heimdal - to avoid the consensus process for testing purposes.

The commit also includes support code to help the delivery of additional
contract based scenratios.
