PCU_Tests_RAW.ttcn: fix ToA handling in as_ta_ptcch()

As it turns out, it was a bad idea to use a counter in altstep
as_ta_ptcch(), because its value is getting lost. Let's instead
introduce a new type PTCCH_TAI_ToA_MAP, which is basically a
list of ToA values for each PTCCH/U sub-slot (TA Index), and
pass it to the altstep.
