Martin Povišer f8325f66b7 opt_expr: Fix 'signed X>=0' replacement for wide output ports ...

If the `$ge` cell we are replacing has wide output port, the upper bits
on the port should be driven to zero. That's not what a `$not` cell with
a single-bit input does. Instead opt for a `$logic_not` cell, which does
zero-pad its output.

Fixes #3867.
