Generate state_dump even on failure

[JulianGCalderon]

Refactors the execution module to always generate a state_dump, even if the transaction fails to execute.

To do this, I created a new function execute_and_process_tx that wraps execute_tx, and processes the result of the transaction, that is:

• Create state dump (always).
• Create libfunc profile.
• Log the result.

Also, we were returning Result<TransactionExecution>, where TransactionExecution also contains a Result, I unified both results into a single Result<TransactionExecution, where TransactionExecution now doesn't contain Result. This allows us to handle the error case more easily.
