params: remove EIP150Hash from chainconfig (#27087) 
The EIP150Hash was an idea where, after the fork, we hardcoded the forked hash as an extra defensive mechanism. It wasn't really used, since forks weren't contentious and for all the various testnets and private networks it's been a hassle to have around. 

This change removes that config field.
