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:

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:

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.

Joost VandeVondele ee6fc7e38b CI: limit artifact uploads
do not upload some unneeded intermediate directories,
disable running authenticated git commands with the checkout action.

Thanks to Yaron A for the report.

DisservinandJoost VandeVondele de2244284b Remove COMPILER from Makefile
The same functionality is available by using COMPCXX and having another variable which does the same is just confusing.
There was only one mention on Stockfish Wiki about this which has been changed to COMPCXX.

Disservin a20726eb0b Refactor the CI workflows
This refactors the CI workflows to group some
logic and makes sure that all (pre)release
binaries are actually tested.

The screenshot below shows the execution logic of
the reworked ci,
https://github.com/Disservin/Stockfish/actions/runs/7773581379.
You can also hover over the cards to see the
execution flow.

The `matrix.json` and `arm_matrix.json` define the
binaries which will be uploaded to GitHub.
Afterwards a matrix is created and each job
compiles a profile guided build for that arch and
uploads that as an artifact to GitHub. The
Binaries/ARM_Binaries workflow's are called when
the previous step has been completed, and uploads
all artifacts to the (pre)release.

This also fixes some indentations and renames the
workflows, see
https://github.com/official-stockfish/Stockfish/actions,
where every workflow is called `Stockfish` vs
https://github.com/Disservin/Stockfish/actions. It
also increases the parallel compilation used for
make from `-j2 to -j4`.

It now also prevents the prerelease action from
running on forks.

A test release can be viewed here
https://github.com/Disservin/Stockfish/releases.
