[idd] audio: support 32-bit and common channel layouts

Browse Source 
Advertise signed and floating-point 32-bit formats across mono,
stereo, quad, surround, 5.1, and 7.1 at every supported rate.

Carry sample encoding through the broker and LGMP protocol so integer
and floating-point streams remain distinct.

Expand packet, shared-memory, and ring capacity for eight-channel
32-bit audio.
