feat: Trusted Builder MVP(W.I.P)

[bharath-123]

Summary

This PR describes the changes made to the composer and conductor for the Trusted Builder MVP.

Background

A Trusted Builder is a sophisticated rollup entity who is responsible for creating high value bundles. Composer is part of the trusted builder. The trusted builder's composer is responsible for simulating the bundle created by the builder and removing any invalid or reverting txs. To achieve this, we have made changes to the ExecuteBlock method/ to have a simulateOnly mode and to return txs that have been successfully included in a block.

More details on Trusted Builder are included in https://www.notion.so/astria-org/Trusted-Block-Builder-MVP-8eba7cd7cbd34e4e90a4adf726879028?pvs=4

Changes

• Update ExecuteBlock method to take in a field simulateOnly which indicates that the ExecuteBlock run is only for simulation.
• Update ExecuteBlock method to return the included transactions list along with the returned block.
• Add a BundleSimulator type which is responsible for simulating a given bundle. To simulate, we call GetCommitmentState followed by an ExecuteBlock with simulateOnly as true. We then create a BuilderBundlePacket with the included transactions and submit it to the sequencer.
• We update the ExecutionAPI protos and add some boilerplate for the BuilderBundle and BuilderBundlePacket protos to convert it from the raw protobuf and the original struct.
