Handle forks (different aztec version) in Inbox/outbox/registry

[rahul-kothari]

Currently the inbox, outbox simply call the latest version of the rollup. Similarly the rollup posts/consumes messages only from the latest version of the inbox/outbox. This won't work for different aztec versions.

Storing version in these contracts also doesn't work because what if an Outbox is used for multiple contracts.

Changes are also expected in the portal contracts and the L1<>L2 e2e test
