* examples : use xcframework in whisper.objc example
This commit updates the whisper.objc example to use the xcframework.
The motivation for this to be consistent with the swift example and to
also act as a reference for how to use the xcframework in an objc
project.

* examples : setup audio session viewDidload
This commit adds the setup of the audio session in the viewDidload
method of the ViewController.m file. This is necessary to allow the app
to record audio.
The motivation for this is that without this it was not possible to
caputue audio from the microphone. It was possible to click on the
Capture button but nothing happened after that, and the button was not
marked red indicating that the button could be clicked again to stop
capturing. With this change it is possible to capture audio from the
microphone and get it transcribed.
This commit adds the GGML_USE_CPU=ON flag to the whisper.objc project in
order to enable the CPU backend for the whisper.objc project.
The motivation for this change is that currently the following error
is generated when running the example:
```console
ggml_backend_buffer_type_t ggml_backend_get_default_buffer_type(ggml_backend_t backend) {
return ggml_backend_dev_buffer_type(backend->device); <- Thread 1: EXC_BAD_ACCESS (code=1, address=0x70)
}
```
If we inspect the `backend` variable we can see that it is a `nullptr`.
```console
(lldb) p backend
(ggml_backend_t) nullptr
```
When running in a simulator and that automatically means that there will
be no gpu as there is a check for this in the code. But the CPU backend
should still be present.
The objective-c code will compile the whisper sources including the ggml
sources. And if `-DGGMLL_USE_CPU` is not defined then there will be no
CPU backend, and in this particular case of backend at all.

* examples : add dl to the list of libraries linked
This commit adds the dynamic linker library to the list of libraries
linked by the examples.
The motivation for this change is that when building the examples on
ubuntu 20.04, which uses GCC 9.4.0, the dynamic linker requires
explicit linking or the following error is generated:
```console
[ 64%] Linking CXX executable ../../bin/whisper-cli

* feat: Add beam size parameter to stream.cpp for beam search configuration
* feat: Add beam size parameter to whisper full params in stream example
* fix: Remove duplicate beam search size assignment in server.cpp
#Summary
This Merge Request adds a mechanism to generate unique filenames for FFmpeg conversions in whisper_server.cpp. Previously, a single fixed filename was used (e.g., whisper-server-tmp.wav), which could result in unexpected file overwrites under certain circumstances. By generating a unique filename per request, any risk of overwriting temporary files is eliminated.
#Background / Motivation
• Problem: Relying on a static filename for temporary audio files may lead to overwrites if multiple operations occur simultaneously or if the same file name is reused.
• Goal: Dynamically generate unique filenames, ensuring each request or operation uses an isolated temporary file.
* The parameter will suppress non-speech tokens like [LAUGH], [SIGH], etc. from the output when enabled.
* add to whisper_params_parse
* add missing param
* Adding missing CMakeLists.txt include for ggm-cpu needed by whisper.android
* attempt to re-enable CI for JNI android
