1) Fixes a bug introduced in
https://github.com/official-stockfish/Stockfish/pull/5194. Only one
psqtOnly flag was used for two perspectives which was causing
wrong entries to be cleared and marked.
2) The finny caches should be cleared like histories and not at the
start of every search.

Avoid unnecessary creation of accumulator cache
Saves a (currently) 800 KB allocation and deallocation when running
`eval`, not particularly significant and zero impact on play but not
necessary either.

Use capture history to better judge which sacrifices to explore
This idea has been bouncing around a while. @Vizvezdenec tried it a
couple years ago in Stockfish without results, but its recent arrival in
Ethereal inspired him and thence me to try it afresh in Stockfish.
(Also factor out the now-common code with futpruning for captures.)
