bts_feature: Introduce feature to confiure dyn ts as sdcch8 

This feature signals support to configure Osmocom Dynamic Timeslot type
as SDCCH8, on top of historically supported TCH/H and TCH/F.
The idea is that when unneeded, the TS is configured as PDCH, and as
soon as there's need for an SDCCH and there's none available, the TS is
dynamically reconfigured to SDCCH8. Once all logical channels in the
dynamic TS are released and hence becomes free, the BSC will reconfigure
it to PDCH.
