…o VL (#12921)

Enable Nemotron Nano V2 VL to process audio streams embedded in video
inputs alongside the visual frames. Previously, audio and video were
handled as entirely separate modalities, so a video with speech or
music required the user to supply the audio track separately.

In order to do so:

* multimodal loading is extended to optionally load audio from video
  (this requires the introduction of the `av` python packages)
* the nemotron nano modeling file adds the necessary multimodal
  placeholder expansion logic and audio embedding.
* some fixes are made to the serve path to ensure the flag to extract
  audio from video can be specified.

This commit also:
* extends the current chunked prefill interfaces to allow models to
  implement the necessary code to opt-in for audio.
* implements it for nemotron nano.
