* whisper : optional ANEForge encoder backend (Apple Neural Engine)
Runs the Whisper encoder directly on the Apple Neural Engine via ANEForge, an
alternative to the CoreML encoder backend. About 2x faster than the CoreML encoder
and faster than the Metal GPU encoder on M-series, at ~5x lower energy, with the
same transcripts (cosine 0.999 vs the reference encoder).
Mirrors the existing CoreML/OpenVINO seam: fills embd_enc from the external aneforge
package via the same whisper_encode_external path, gated at runtime by the
ANEFORGE_ENCODER env var. With the variable unset the build behaves exactly like
stock whisper.cpp (the backend dlopens its dispatch dylib only when enabled, no new
link-time dependency). Encoder only; the decoder is untouched.
Adds src/aneforge/whisper-aneforge.{h,cpp}, one line to src/CMakeLists.txt, and ~30
lines to src/whisper.cpp (include, state field, encode branch, init, free).
* aneforge: one statement per line, align dlsym block (review)
* aneforge: guard the backend to Apple Silicon, stub elsewhere (fix non-Apple CI)
whisper-aneforge.cpp uses <dlfcn.h> and __fp16, which are unavailable on Windows
(MSVC) and non-ARM Linux, so the unconditional build broke those CI jobs. Wrap the
real implementation in #if defined(__APPLE__) && defined(__aarch64__) and provide
no-op stubs elsewhere; the encoder is Apple-Neural-Engine-only anyway, and the
library now links on every platform.
* examples : include whisper-aneforge.cpp in android examples
Refs: https://github.com/ggml-org/whisper.cpp/actions/runs/32758607709/job/97689705921?pr=3905#step:5:200
* ci : specify explicit packages (platform-tools)
This commit updates the android jobs to specify platform-tools as an
explicit package.
The motivation for this to try to fix the Setup Android SDK step which
is also trying to install an obolete tools package.

* whisper : add version function
This commit adds a version function to the whisper API.
The motivation for this is that it might be convenient to have a way to
programmatically check the version.
Example usage:
```c++
printf("Using whisper version: %s\n", whisper_version());
```
Will output:
```console
Using whisper version: 1.7.6
```
* examples : add version to android example CMakeLists.txt
* android : update CMakeLists.txt to use FetchContent for ggml
This commit updates the CMakeLists.txt file for the Android Whisper
example to use FetchContent for managing the ggml library.
The motivation for this change is avoid having to make manual changes to
the CMakeLists.txt file after syncing the ggml library.
I've built and run the example locally to verify that it works as
expected.

* android.java : update cmake to use FetchContent for ggml
This commit updates the CMake configuration for the Android Java example
to use `FetchContent` for including the `ggml` library. Do be able to
use FetchContent we also update the `compileSdkVersion` and
`targetSdkVersion` to 31, and the `buildToolsVersion` to '30.0.3'.
This also required a an update to the Gradle plugin version to 7.4.0.
The motivation for this change is avoid having to make manual changes to
the CMakeLists.txt file after syncing the ggml library.
This commit add GGML_USE_CPU to built target library to enable CPU
backend.
The motivation for this that without the compile definition the CPU
backend is not enabled and the app will crash when trying to use it.
* Adding missing CMakeLists.txt include for ggm-cpu needed by whisper.android
* attempt to re-enable CI for JNI android

Benchmarks are failing because JNI expects a jstring and the benchmarks
are missing a return statement (i.e., returning null). The functions
actually build a jstring but don't return it, so this seems to have been
an oversight.
This patch returns the jstring and now the benchmarks run successfully.
Fixes#1783.
