coreml : set convert_to="mlprogram" in convert

* coreml : skip model load in convert-whisper-to-coreml.py

This commit updates the conversion process for Whisper models to use the
"mlprogram" format instead of "neuralnetwork".

The motivation for this change is that when using the "neuralnetwork"
format the underlying model produced is based on protobuf and my
understanding is that there are limitations to this format, such as
sizes of strings and the complexity of the model.

Currently when trying to convert larger models such as large-v3 the
conversion fails but succeeds for smaller models.

The "mlprogram" format is a more recent addition to CoreML and is
designed to be more flexible and powerful, allowing for more complex
models and larger data types. This seems to work for larger and smaller
models alike and unless I'm there are considerations that I'm not aware
of I think this is what we should be using moving forward.
The error that is generated for large models is the following:
```console

-## Implementation details
-
-- The core tensor operations are implemented in C ([ggml.h](ggml/include/ggml.h) / [ggml.c](ggml/src/ggml.c))
-- The transformer model and the high-level C-style API are implemented in C++ ([whisper.h](include/whisper.h) / [whisper.cpp](src/whisper.cpp))
-- Sample usage is demonstrated in [main.cpp](examples/main)
-- Sample real-time audio transcription from the microphone is demonstrated in [stream.cpp](examples/stream)
-- Various other examples are available in the [examples](examples) folder
-
-The tensor operators are optimized heavily for Apple silicon CPUs. Depending on the computation size, Arm Neon SIMD intrinsics or CBLAS Accelerate framework routines are used. The latter are especially effective for bigger sizes since the Accelerate framework utilizes the special-purpose AMX coprocessor available in modern Apple products.

+## FFmpeg support (Linux only)
+
+If you want to support more audio formats (such as Opus and AAC), you can turn on the `WHISPER_FFMPEG` build flag to enable FFmpeg integration.
+
+First, you need to install required libraries:
+
+```bash
+# Debian/Ubuntu
+sudo apt install libavcodec-dev libavformat-dev libavutil-dev
+
+# RHEL/Fedora
+sudo dnf install libavcodec-free-devel libavformat-free-devel libavutil-free-devel
+```
+
+Then you can build the project as follows:
+
+```bash
+cmake -B build -D WHISPER_FFMPEG=yes
+cmake --build build
+```
+
+Run the following example to confirm it's working:
+
+```bash
+# Convert an audio file to Opus format
+ffmpeg -i samples/jfk.wav jfk.opus
+
+# Transcribe the audio file
+./build/bin/whisper-cli --model models/ggml-base.en.bin --file jfk.opus

+
+First call of `rake test` builds an extension and downloads a model for testing. After that, you add tests in `tests` directory and modify `ext/ruby_whisper.cpp`.
+
+If something seems wrong on build, running `rake clean` solves some cases.

+# CI
+
+In addition to [Github Actions](https://github.com/ggerganov/whisper.cpp/actions) `whisper.cpp` uses a custom CI framework:
+
+https://github.com/ggml-org/ci
+
+It monitors the `master` branch for new commits and runs the
+[ci/run.sh](https://github.com/ggerganov/whisper.cpp/blob/master/ci/run.sh) script on dedicated cloud instances. This allows us
+to execute heavier workloads compared to just using Github Actions. Also with time, the cloud instances will be scaled
+to cover various hardware architectures, including GPU and Apple Silicon instances.
+
+Collaborators can optionally trigger the CI run by adding the `ggml-ci` keyword to their commit message.
+Only the branches of this repo are monitored for this keyword.
+
+It is a good practice, before publishing changes to execute the full CI locally on your machine:
+
+```bash
+mkdir tmp
+
+# CPU-only build
+bash ./ci/run.sh ./tmp/results ./tmp/mnt
+
+# with CUDA support
+GG_BUILD_CUDA=1 bash ./ci/run.sh ./tmp/results ./tmp/mnt
+```
+
+## Environment Variables
+
+The CI script supports several environment variables to control the build:
+
+| Variable | Description |
+|----------|-------------|
+| `GG_BUILD_CUDA` | Enable NVIDIA CUDA GPU acceleration |
+| `GG_BUILD_SYCL` | Enable Intel SYCL acceleration |
+| `GG_BUILD_VULKAN` | Enable Vulkan GPU acceleration |
+| `GG_BUILD_METAL` | Enable Metal acceleration on Apple Silicon |
+| `GG_BUILD_BLAS` | Enable BLAS CPU acceleration |
+| `GG_BUILD_OPENVINO` | Enable OpenVINO support |
+| `GG_BUILD_COREML` | Enable Core ML support for Apple Neural Engine |
+| `GG_BUILD_LOW_PERF` | Limit tests for low-performance hardware |
+| `GG_BUILD_TEST_MODELS` | Comma-separated list of models to test (e.g. "tiny.en,tiny,base,medium", defaults to all models unless `GG_BUILD_LOW_PERF` is set) |
