Make low ply history size fixed

Size of low ply history should always be the same, so ensure it.

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/ ... 47d953d226
https://tests.stockfishchess.org/tests/ ... be9d4eccea

The implementation approach was suggested by Disservin.
