TMXR: Rework modem signaling support

Browse source 
- Fix ineffective setting of RNG modem bit when line with DTR isn't available
- Fix logic clearing modem signal bits
- Add API to set/clear modem control behavior fo a specific line.
- return -2 status from tmxr_poll_conn when RNG has been enabled
