Simplify statscore at captures

Simplify statscores for captures, setting them to 0

A recent tweak of Vizvezdenec finds substantial elo gain from giving
captures a separate statscore, which is used mainly for reductions. The
idea is that the old combination of quiet histories was inappropriate
and that a value based on the capture history is more suitable. This
simplification sets the statscore for captures to 0, suggesting that the
elo gain came from rectifying the quiet history/capture mismatch.

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:

Small cleanup for stats adjustments

After some simplifications bonuses and maluses are the same for quiet
and non-quiet moves so it makes no sense to use quietMoveBonus/Malus,
instead use just bonus/malus.

Speedup Makefile on Windows

The Makefile is notoriously slow on windows, because of new processes
being spawned I believe. This pr improves it a little bit for the help
and config-sanity targets, with the latter also improving `make -j
build` because it depends on that. On the same machine ubuntu (wsl) is
more than 3 times faster, if there are other improvements we can make
I'd be happy to hear about them. Ultimately
https://github.com/official-stockfish/Stockfish/pull/5543 also aims to
improve this I believe, but it will take some additional time before
that lands.

```
make config-sanity:

patch: 6.199s
master: 12.738s

make help:

patch: 3.1s
master: 11.49s

make -j build:

patch: 36s
master: 43.25s

make -j build:

master ubuntu: 10s
```
