erts: Stop supporting non-literal empty tuples

Since R12B, empty tuples are literals. Thus the compiler will no
longer generate the instruction:

  put_tuple 0 Destination

for creating an empty tuple. It is now time to stop supporting
that instruction in the run-time system.

While we are at it, correct a typo.
