Print NEON before POPCNT in compilation settings
...
Normally, Stockfish outputs the compilation settings from advanced to less
advanced, e.g.: `AVX512ICL VNNI AVX512 BMI2 AVX2 SSE41 SSSE3 SSE2 POPCNT`
With NEON, however, POPCNT is printed first, followed by the more advanced NEON
options: `POPCNT NEON_DOTPROD`
This PR places POPCNT behind the NEON options as well.

Fix dotprod detection
...
This fixes the detection of dotprod capable CPUs. Previously it looked
for the `dotprod` flag, but this does not exist
(https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/arch/arm64/kernel/cpuinfo.c#n50 ).
The correct flag that specifies the dotprod capability is the `asimddp`
flag.
fixes #4931

Always output hashfull
...
This removes the restriction that no hashfull information is printed within the first second of a search.
On modern systems, a non-zero value is returned within 6 ms with default settings.

Update default net to nn-ac5605a608d6.nnue
...
This net was created with the nnue-pytorch trainer, it used the previous master net as a starting point.
The training data includes all T60 data (https://drive.google.com/drive/folders/1rzZkgIgw7G5vQMLr2hZNiUXOp7z80613 ), all T74 data (https://drive.google.com/drive/folders/1aFUv3Ih3-A8Vxw9064Kw_FU4sNhMHZU- ) and the wrongNNUE_02_d9.binpack (https://drive.google.com/file/d/1seGNOqcVdvK_vPNq98j-zV3XPE5zWAeq ). The Leela data were randomly named and then concatenated. All data was merged into one binpack using interleave_binpacks.py.
