rABCb9af6d5b906c: validation: add CChainState::m_disabled and ChainMan::isUsable

Summary

and remove m_snapshot_validated. This state can now be inferred by the
number of isUsable chainstates.

m_disabled is used to signal that a chainstate should no longer be used
by validation logic; it is used as a sentinel when background validation
completes or if the snapshot chainstate is found to be invalid.

isUsable is a convenience method that incorporates m_disabled.

This is a partial backport of core#25740

1146	Can we rename the param to pchainstate or something similar ? cs usually stands for critical section, hence cs_main so this is confusing as it sounds like a mutex
