Stockfish prerelease 20241031:
Remove moveCountPruning in search.cpp

The definition of moveCountPruning may cause confusion by implying that
the variable is unconstrained. However, once it is set to true, it
should not be reset to false, otherwise it would break the internal
logic of MovePicker.

Several patches have overlooked this constraint. For example:

https://tests.stockfishchess.org/tests/view/66a1de7b4ff211be9d4eccea

The implementation approach was suggested by Disservin.
