Update inactivity penalty deltas processing 
Two main changes:

1. Inactivity scores are modified to decrease slowly for inactive validators when we are not in a leak, and quickly for active validators
2. The inactivity penalties are applied even not during a leak (note that inactivity _scores_ decrease when outside of a leak)

This has the effect that the inactivity leak "overshoots" the target of finalizing again, and keeps leaking balances a bit more. For inactive validators, this PR sets post-leak recovery to happen 3x faster than the during-leak increase, so if a validator loses 3% during a leak, if they stay offline they should expect to lose another 1% until their score decreases back to zero.

Reorganization of config params to put sync committee in one section 
This may be marginally "cleaner" than the previous approach, keeping constants with the same topic together.
