ppigazziniandJoost VandeVondele 3ee16a1d8e refactor(scripts): improve get_native_properties.sh 
Improve `get_native_properties.sh` with a refreshed implementation.
The new version covers all Makefile ARCH variants and keeps the
script interface stable while improving portability and CPU feature
detection across supported platforms. Drop the asset file name to
avoid coupling outputs to a specific artifact naming scheme.

Refs: https://github.com/ppigazzini/get-native-properties (includes a
testing framework)

ppigazziniandJoost VandeVondele 0317c6ccec build: rename WINE_PATH to RUN_PREFIX for wrapper execution 
WINE_PATH started as a Wine-specific knob, but it’s now used more generally
as a command prefix to run the built engine under wrappers
like Intel SDE, qemu-user, etc.

- Add RUN_PREFIX as the supported “run wrapper/prefix” variable in Makefile
- Set WINE_PATH as a deprecated alias
- Update CI and scripts to use RUN_PREFIX

ppigazziniandJoost VandeVondele e3adfaf8fc build & ci: update to NDK r27c API level 29 
Update to the latest LTS version NDK r27c (27.2.12479018),
the previous NDK are unsupported by Google, see:
https://developer.android.com/ndk/downloads

A build with NDK r27c and API level < 29 returns this error:
"executable's TLS segment is underaligned: alignment is 8 (skew 0), needs to be at least 64 for ARM64 Bionic"

Update the API level to 29 to use the native ELF LTS and avoid the error:
https://android.googlesource.com/platform/bionic/+/HEAD/docs/elf-tls.md
https://android.googlesource.com/platform/bionic/+/HEAD/android-changes-for-ndk-developers.md#elf-tls-available-for-api-level-29

A dynamic link build of Stockfish uses these libraries:

ldd stockfish-android-armv8-dynamic-api35
        libm.so => /system/lib64/libm.so
        libdl.so => /system/lib64/libdl.so
        libc.so => /system/lib64/libc.so
        ld-android.so => /system/lib64/ld-android.so

ld-android.so : the dynamic linker used by Android (on Linux is named ld-linux.so),
                responsible for loading and linking shared libraries into an executable at runtime.
libdl.so      : interface/library layer that provides function for dynamic loading,
                relies on the underlying functionality provided by the dynamic linker
libm.so       : math library for Android
libc.so       : standard C library for Android

NDK r27c build system:
https://android.googlesource.com/platform/ndk/+/ndk-r27-release/docs/BuildSystemMaintainers.md

CI: Update to NDK r27c (27.2.12479018), the default version in GitHub runner,
to switch to a recent clang 18.

A PGO build requires static linking, because the NDK doesn't ship
the Android loaders (linker/linker64), see:
https://groups.google.com/g/android-ndk/c/3Ep6zD3xxSY

The API level should not be an issue when distributing a static build,
use the API 29, the oldest one not affected by the LTS alignement issue.

ppigazziniandJoost VandeVondele 9a2d50eccc Make posix and msys2 shells consistent in CI 
In CI, it is typical for the process to halt immediately when an error
is encountered. However, with our `shell: bash {0}` configuration,
the process continues despite errors for posix shells.
This commit updates the behavior of posix and msys2 shells to ensure
consistency in terms of pipeline exit codes and stop conditions.
We adopt the most appropriate default behavior as recommended
by the GitHub documentation.

Update the code that searches for the bench value in the git log:
- to be compatible with the new shell settings
- to retry the value from the first line that contains
  only the template and spaces/tabs/newlines

ppigazziniandJoost VandeVondele 2da1d1bf57 Add ARM NDK to Github Actions matrix 
- set the variable only for the required tests to keep simple the yml file
- use NDK 21.x until will be fixed the Stockfish static build problem
  with NDK 23.x
- set the test for armv7, armv7-neon, armv8 builds:
  - use armv7a-linux-androideabi21-clang++ compiler for armv7 armv7-neon
  - enforce a static build
  - silence the Warning for the unused compilation flag "-pie" with
    the static build, otherwise the Github workflow stops
  - use qemu to bench the build and get the signature

Many thanks to @pschneider1968 that made all the hard work with NDK :)

ppigazziniandJoost VandeVondele 67062637f4 Improve Makefile for Windows native builds 
A Windows Native Build (WNB) can be done:
 - on Windows, using a recent mingw-w64 g++/clang compiler
   distributed by msys2, cygwin and others
 - on Linux, using mingw-w64 g++ to cross compile

Improvements:
 - check for a WNB in a proper way and set a variable to simplify the code
 - set the proper EXE for a WNB
 - use the proper name for the mingw-w64 clang compiler
 - use the static linking for a WNB
 - use wine to make a PGO cross compile on Linux (also with Intel SDE)
 - enable the LTO build for mingw-w64 g++ compiler
 - set `lto=auto` to use the make's job server, if available, or otherwise
   to fall back to autodetection of the number of CPU threads
 - clean up all the temporary LTO files saved in the local directory

Tested on:
 - msys2 MINGW64 (g++), UCRT64 (g++), MINGW32 (g++), CLANG64 (clang)
   environments
 - cygwin mingw-w64 g++
 - Ubuntu 18.04 & 21.10 mingw-w64 PGO cross compile (also with Intel SDE)
