contracts-bedrock: fee vault track total value 

Adds an accumulator for the total amount of fees
withdrawn from the system. This is really helpful for
data analytics. I also think it could be used to build
an on chain prediction market for economic activity.
This code path isn't triggered too often, so an extra
sload/sstore and checked math doesn't matter much.
