Add KNNvKP Endgame Heuristic

This is a somewhat different patch. It fixes blindspots for
two knights vs pawn endgame.

With local testing starting from random KNNvKP positions where the
pawn has not advanced beyond the 4th rank (thanks @protonspring !)
at 15+0.15 (4 cores), this went +105=868-27 against master. All except
two losses were won in reverse.

The heuristic is simple but effective - the strategy in these endgames
is to push the opposing king to the corner, then move the knight that's
blocking the pawn in for the checkmate while the pawn is free to move
and prevents stalemate. This patch gives SF the little boost it needs
to search the relevant king-cornering mating lines.

See the discussion in pull request 1939 for some more good results for
this test in independant tests:

ProbCutCount limit dependancy to cutNode

Use the ProbCutCount limit `2 + 2 * cutNode` instead of constant 3.

Remove PvNode dimension from Reductions array

This is a functional simplification: if we simply subtract one to Reductions[]
when PvNode is set, we can remove this dimension of the multidimensional array.
I think this saves about 8K of memory.

Remove skipQuiets variable in search()

This is a functional simplification. The moveCountPruning variable and the
skipQuiets variable are similar enough in function that they can be combined.
This removes the skipQuiets variable in search.
