declare a few variables atomic.

e8472b5fbe Fix races in gensfen as detected with thread sanitizer. 
RootInTB was an incorrectly shared global, probably leading to wrong scoreing

Minor:
 setting TB global state from input by all threads (all threads write same values)
 setting Limits global state by all threads (idem)
 thread counting for finalization

CI can be enabled once races are fixed in the learner, manually goes like:
```
make clean && make -j2 ARCH=x86-64-modern sanitize=thread    optimize=no debug=yes build
../tests/instrumented_learn.sh --sanitizer-thread
```

Needs some review.

8b8a510fd6 Use tiling to speed up accumulator refreshes and updates 
Perform the update and refresh operations tile by tile in a local
array of vectors. By selecting the array size carefully, we
achieve that the compiler keeps the whole array in vector registers.

Idea and original implementation by @sf-x.

d86663af14 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.

5f426d8667 Use 2 * bestMoveChanges. 
NNUE appears to provide a more stable eval than the classic eval,
so the time use dependencies on bestMoveChanges, fallingEval,
etc may need to change to make the best use of available time.
This change doubles the effect of totBestMoveChanges when giving
more time because the choice of best move is unstable.
