This PR changes geth to read the eip1559 params from the chain config instead of the globals. This way the parameters may be changed by forking the chain config code, without creating a large diff throughout the past and future usages of the parameters.

This PR changes geth to read the eip1559 params from the chain config instead of the globals.
This way the parameters may be changed by forking the chain config code, without creating a large diff throughout the past and future usages of the parameters.
Like with hardforks and testnets, geth can support different options at the same time, because the parameters are not hardcoded. This PR does not make the parameters configurable with new individual fields however, to follow the pattern where parameters are determined by hardfork/consensus-type. This PR does not introduce any new format or new branching logic.
See #25822 for context.
