[Ada] Update FE check following change in SPARK RM 7.1.3(12)
SPARK Reference Manual changed to accept attributes First, Last and Length
as not leading to an evaluation of a part of the prefix object. This is
reflected here in the checking code for that rule.

* sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and
