library/RSL_Types: fix CHAN ACT templates for dynamic timeslots

* t_RSL_IE_ActType_PDCH is actually a constant, not a template.
* tr_RSL_CHAN_ACT_PDCH makes no use of parameter 'mode'.
* Accomplish tr_RSL_CHAN_ACT_PDCH with a send template.
* Use 'present' qualifier for receive template parameters.
