SVM: Group transaction processing configs

[buffalojoec]

Problem

The SVM's transaction processing functions - load_and_execute_sanitized_transactions
and execute_loaded_transaction - are quickly becoming overloaded with inputs.

Since many of these inputs are optional configurations to customize transaction
processing behavior, it makes sense to group these together, in a type that implements
Default, and require only a reference to said type to process transactions.

This would make integrating the transaction processor's API with a set of configs much
more idiomatic.

Summary of Changes

Group all optional configurations for processing transactions into a new configuration
object: TransactionProcessingConfig and require a reference to this object in the
SVM API.
