SugaR v5.3 RC2 32-64 Engine

SugaR v5.3 RC2 32-64
Split PSQT init from Position init

https://github.com/Zerbinati/SugaR/commit/da561e4fef63aa5436e60faf7688d19bfbf22990
Easier for tuning psq tables:

TUNE(myParameters, PSQT::init);

Also move PSQT code in a new *.cpp file, and retire the
old and hacky psqtab.h that required to be included only
once to work correctly, this is not idiomatic for a header
file.

Give wide visibility to psq tables (previously visible only
in position.cpp), this will easy the use of psq tables outside
Position, for instance in move ordering.

Finally trivial code style fixes of the latest patches.

Original patch of Lucas Braesch.

No functional change.

Halve PSQT row data
https://github.com/Zerbinati/SugaR/commit/0b7f4e06381146e33ee915f6df846b71e120eec5
Use symmetry along vertical middle axis of the board
to reduce the number of parameters.

For instance psqt value of SQ_A5 == SQ_A4 and value of
SQ_F8 == SQ_F1.

This is always true, at least until now nobody came in
with an asymmetric psqt table that worked.

Original patch by Lucas.

No functional change.
