Move internal iterative reduction before probcut
This patch moves IIR before probcut which allows probcut
to be produced at lower depths. Comments in IIR are also slightly updated.

Simplify away SEE verification
After 4 simplificatons over PR#4453 the idea does not yield significant

Search tuning at very long time control with new net
The most significant change would be the singularBeta formula.
It was first tested by cj5716 (see https://tests.stockfishchess.org/tests/view/647317c9d29264e4cfa74ec7),
and I took much inspiration from that idea.
