sound: HDA support with PCM and wav playback

- Implemented HDA driver in src/sound/hda.c, providing initialization, codec enumeration, and playback functionality.
- Defined HDA register offsets and structures in src/sound/hda.h.
- Added WAV file parsing and playback capabilities in src/sound/pcm.c, supporting both WAV and raw PCM formats.
- Created header file src/sound/pcm.h for PCM playback functions and WAV header structures.
- Integrated memory management for DMA buffers during audio playback.

Yes we played Charlie Charlie Kirky as the first sound on KirkOS
