[raudio] Audio recording

[jn-jairo]

This PR adds basic audio recording.

Notes:

• Separated from audio playback
• InitAudioRecordingDevice() uses defines for config (the same one from playback)
• InitAudioRecordingDeviceEx() uses custom sampleRate, sampleSize and channels
• Callback to receive data is set with SetAudioRecordingCallback()
• Added AudioRecordingCallback callback instead of using AudioCallback because the input data is const void * instead of the void * of the output and the compiler was showing a warning, if it's ok to use AudioCallback and ignore the warning I can change it
• Added function to get the recording configs GetAudioRecordingSampleRate(), GetAudioRecordingSampleSize() and GetAudioRecordingChannels() because it is needed to process the data as shown in the example
• StartAudioRecording() and StopAudioRecording() use the ma_device_start() and ma_device_stop(), so the capture device is not always running like the playback one, and the recording status is if the device is started
• Added an example that records up to 5 seconds of audio and play it back

This interface is the simplest I got that enables all use cases I could imagine.

In games audio recording is mainly for voice chat and a stream of data is all you need.

For other softwares like audio recording/editing, you would need to be able to set the sample rate and so on at runtime, that is why I added this option, and creating a wave is trivial if you have the stream of data like shown in the example, so we don't need to have it builtin in raylib.

Please let me know if there is anything I need to change. I tested in Linux (kubuntu 24.04) with zig and make, I didn't commit the changes in the makefile because I believe there is a rexm to manage that but it is crashing when I try to add the example.

It's an example of an alternative method to initialize the audio recording device.
