This adds retries when dialing ethclient or rollupclient RPC urls.
Because this now does up to 10 exponential backoffs, the dial timeout
has been increased to 15s (though this may not be enough).

I have also modified the API to DialClient to no longer take a context.
This is because we are not sharing the context & if we want to pass in
a context, we should probably set the timeout outside the dial function.

contracts-bedrock: erc721 bridge single impl

Update the ERC721 bridge so that a single implementation
can be used across many different chains.

Still need to double check the storage layout before this
is good, but the tests are passing.

Also need to update all the code that touches the go bindings.
