Speedup protorev by having route calculation phase not unmarshal pools (backport #8157)

[mergify]

What is the purpose of the change

This is an expected .7% speedup to block syncing. It works by having protorev not unmarshal every pool in route cost estimation phase. It is state breaking due to gas differences.

Testing and Verifying

This adds a test to ensure that the new GetPoolType method returns a deterministic amount of gas.
