New NNUE architecture and net
...
Introduces a new NNUE network architecture and associated network parameters,
as obtained by a new pytorch trainer.
The network is already very strong at short TC, without regression at longer TC,
and has potential for further improvements.

The network has been trained (by vondele) using the https://github.com/glinscott/nnue-pytorch/ trainer (started by glinscott),
specifically the branch https://github.com/Sopel97/nnue-pytorch/tree/experiment_56 .
The data used are in 64 billion positions (193GB total) generated and scored with the current master net

This network also contains a few architectural changes with respect to the current master:
Size changed from 256x2-32-32-1 to 512x2-16-32-1
~15-20% slower
~2x larger
adds a special path for 16 valued ClippedReLU
fixes affine transform code for 16 inputs/outputs, buy using InputDimensions instead of PaddedInputDimensions
this is safe now because the inputs are processed in groups of 4 in the current affine transform code
The feature set changed from HalfKP to HalfKAv2
Includes information about the kings like HalfKA
Packs king features better, resulting in 8% size reduction compared to HalfKA
The board is flipped for the black's perspective, instead of rotated like in the current master
PSQT values for each feature
the feature transformer now outputs a part that is fowarded directly to the output and allows learning piece values more directly than the previous network architecture. The effect is visible for high imbalance positions, where the current master network outputs evaluations skewed towards zero.
8 PSQT values per feature, chosen based on (popcount(pos.pieces()) - 1) / 4
initialized to classical material values on the start of the training
8 subnetworks (512x2->16->32->1), chosen based on (popcount(pos.pieces()) - 1) / 4
only one subnetwork is evaluated for any position, no or marginal speed loss

Allow using Intel SDE for PGO builds.
...
The software development emulator (SDE) allows to run binaries compiled
for architectures not supported by the actual CPU. This is useful to
do PGO builds for newer architectures. The SDE can currently be obtained from
https://software.intel.com/content/www/us/en/develop/articles/intel-software-development-emulator.html
This patch introduces a new optional makefile argument SDE_PATH.
If not empty it should contain the path to the sde executable

Improve NDK section in Makefile
...
This PR sets the "comp" variable simply to "clang",
which seems to be more consistent and allows a small simplification.
The PR also moves the section that sets "profile_make" and "profile_use" to after the NDK section,
which ensures that these variables are now set correctly for NDK/clang.
