feat(contracts/solve): gas optimized SolverNetInbox open flow

[Zodomo]

I significantly reduced gas costs for SolverNetInbox's open() function. This was done by storing the OnchainCrossChainOrder struct rather than the complex ResolvedCrossChainOrder struct. Then, in any function that relies on the ResolvedCrossChainOrder, it is resolved again for these functions. The majority of the gas savings were found in open, but all of the other order functions saw gas reductions too. We can likely go way further than this ~20% reduction in costs, but this was what I could squeeze out without any impact to the solver. The interface remains entirely unchanged.

Here are gas reports for the impacted functions:

issue: #2917

[Zodomo]

Closed as this implementation was deprecated by the one in #2954, which achieved far better optimization.
