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

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.
