Enable 32-bit color depths

Browse Source 
To enable 32-bit color depths a earlyCapabilityFlag in the CS_CORE
packet is required. When 32-bit color depth is requested, this
RNS_UD_CS_WANT_32BPP_SESSION flag will now be set. We also advertise
support for 32-bit color depths through the RNS_UD_32BPP_SUPPORT flag.
