rABC4ee2470e29ce: [refactor] Add useful-for-dos "reason" field to CValidationState

Summary

This is a first step towards cleaning up our DoS interface - make
validation return *why* something is invalid, and let net_processing
figure out what that implies in terms of banning/disconnection/etc.

Behavior change: peers will now be banned for providing blocks
with premature coinbase spends.

src/consensus/validation.h
39 ↗	(On Diff #21675)	That comment needs some segwit clearance. Not sure the enum makes much sense for us at all.
src/validation.cpp
1740 ↗	(On Diff #21675)	Note to reviewers: the behavior changed in D6693, now the ban happen in CheckInputs.
