offchainDebugEval

A more explicit/open version of eval that is designed for offchain debugging. It MUST function identically to eval so implementations MAY call it directly internally for eval to ensure consistency at the expense of a small amount of gas. The affordances made for debugging are:

• A fully qualified namespace is passed in. This allows for storage reads from the perspective of an arbitrary caller during eval. Note that it does not allow for arbitrary writes, which are still gated by the store contract itself, so this is safe to expose.
• The bytecode is passed in directly. This allows for debugging of bytecode that has not been deployed to the chain yet.
• The components of the encoded dispatch other than the onchain expression address are passed separately. This remove the need to provide an address at all.
• Inputs to the entrypoint stack are passed in directly. This allows for debugging/simulating logic that could normally only be accessed via. some internal dispatch with a mid-flight state creating inputs for the internal call.
