bts: use feature list instead of speech codec table

osmo-bts has a table of pchan/channel mode combinations for every
bts. This table models the codec capabilitys of the BTS hardware.
However, having the speech codec apabilities modeled inside the
BTS feature list would be much more comfortable and since the
feature list is communicated back to the BSC we would get the
codec capabilities inside the BSC domain as well.

- remove the pchan/channel mode tables
- set speech codec variants for each BTS type
- fix bts_supports_cm so that it queries the feature list
