feat(whisper-cpp): Convert to Purego and add VAD (#6087)
* fix(ci): Avoid matching wrong backend with the same prefix

Signed-off-by: Richard Palethorpe <io@richiejp.com>

* chore(whisper): Use Purego and enable VAD

This replaces the Whisper CGO bindings with our own Purego based module
to make compilation easier.

In addition this allows VAD models to be loaded by Whisper. There is not
much benefit now except that the same backend can be used for VAD and
transcription. Depending on upstream we may also be able to use GPU for
VAD in the future, but presently it is disabled.
