webrtc: add android webrtcsrc example

Browse source 
This commit adds an Android `webrtcsrc` based example with the following
features:

* A first view allows retrieving the producer list from the signaller (peer ids
  are uuids which are too long to tap, especially using an onscreen keyboard).
* Selecting a producer opens a second view. The first available video stream is
  rendered on a native Surface. All the audio streams are rendered using
  `autoaudiosink`.

Available Settings:

* Signaller URI.
* A toggle to prefer hardware decoding for OPUS, otherwise the app defaults to
  raising `opusdec`'s rank. Hardware decoding was moved aside since it was found
  to crash the app on all tested devices (2 smartphones, 1 tv).

**Warning**: in order to ease testing, this demonstration application enables
unencrypted network communication. See `AndroidManifest.xml`.

The application uses the technologies currenlty proposed by Android Studio when
creating a new project:

* Kotlin as the default language, which is fully interoperable with Java and
  uses the same SDK.
* gradle 8.6.
* kotlin dialect for gradle. The structure is mostly the same as the previously
  preferred dialect, for which examples can be found online readily.
* However, JNI code generation still uses Makefiles (instead of CMake) due to
  the need to call [`gstreamer-1.0.mk`] for `gstreamer_android` generation.
  Note: on-going work on that front:
  - https://gitlab.freedesktop.org/gstreamer/cerbero/-/merge_requests/1466
  - https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/6794

Current limitations:

* x86 support is currently discarded as `gstreamer_android` libs generation
  fails (observed with `gstreamer-1.0-android-universal-1.24.3`).
* A selector could be added to let the user chose the video streams and
  possibly decide whether to render all audio streams or just select one.

Nice to have:

* Support for the synchronization features of the `webrtc-precise-sync-recv`
  example (NTP clock, RFC 7273).
* It could be nice to use Rust for the specific native code.

## Android
### `webrtcsrc` based Android application
An Android demonstration application which retrieves available producers from
the signaller and renders audio and video streams.
**Important**: in order to ease testing, this demonstration application enables
unencrypted network communication. See `app/src/main/AndroidManifest.xml` for
details.
#### Build the application
* Download the latest Android prebuilt binaries from:
https://gstreamer.freedesktop.org/download/
* Uncompress / untar the package, e.g. under `/opt/android/`.
* Define the `GSTREAMER_ROOT_ANDROID` environment variable with the
directory chosen at previous step.
* Install a recent version of Android Studio (tested with 2023.3.1.18).
* Open the project from the folder `android/webrtcsrc`.
* Have Android Studio download and install the required SDK & NDK.
* Click the build button or build and run on the target device.
* The resulting `apk` is generated under:
`android/webrtcsrc/app/build/outputs/apk/debug`.
For more details, refer to:
* https://gstreamer.freedesktop.org/documentation/installing/for-android-development.html
Once the SDK & NDK are installed, you can use `gradlew` to build and install
the apk (make sure the device is visible from adb):
```shell
# From the android/webrtcsrc directory
./gradlew installDebug
```
#### Install the application
Prerequisites: activate developer mode on the target device.
There are several ways to install the application:
* The easiest is to click the run button in Android Studio.
* You can also install the `apk` using `adb`.
Depending on your host OS, you might need to define `udev` rules. See:
https://github.com/M0Rf30/android-udev-rules
#### Setup
1. Run the Signaller from the `gst-plugins-rs` root directory:
```shell
cargo run --bin gst-webrtc-signalling-server
```
2. In the Android app, tap the 3 dots button -> Settings and edit the Signaller
URI.
3. Add a producer, e.g. using `gst-launch` & `webrtcsink` or run:
```shell
cargo r --example webrtc-precise-sync-send
```
4. Click the `Refresh` button on the Producer List view of the app.

/* Android GStreamer WebRTCSrc native code.
*
* The following file implements the native logic for an Android application to be able to
* to start an audio / video stream from a producer using GStreamer WebRTCSrc. This is designed
* to work in tandem with the managed Kotlin class `WebRTCSrc`.
*
* - The managed class is in charge of spawning an event loop, initializing the native libraries and
* scheduling calls to native functions (such as `startPipeline`, `stopPipeline`, `setSurface`, ...).
* The native implementation of these functions expects the calls to be handled one at a time,
* which is the case when scheduling is handled by an `android.os.Handler`.
* - See the `native_methods[]` for the mapping between the managed class and the native functions.
* - See also the comment for `attach_current_thread()` regarding calling managed call from a thread
* spawned by C code.
