Enabling usage of ulsyncvalidityDuration timer in SIB19

ntn-UlSyncValidityDuration in SIB19 from Spec 38.331 v17.12 A validity
duration configured by the network for assistance information which
indicates the maximum time duration (from epochTime) during which the UE
can apply assistance information without having acquired new assistance
information. The unit of ntn-UlSyncValidityDuration is second. Value s5
corresponds to 5 s, value s10 indicate 10 s and so on.

    ntn-UlSyncValidityDuration-r17 ENUMERATED{ s5, s10, s15, s20, s25, s30, s35,s40, s45, s50, s55, s60, s120, s180, s240, s900}

Implementation of epochtime is under discussion.

It can be configured in configuration file according to the above
enumeration. For GEO - 240s, MEO - 20s, LEO-5s can be used.
