Improve directed infinity (#809)

This is based on one part of #766 related to how DirectedInfinity is handled. To simplify this, I remove part of the `eval_Times` code handling this kind of expression and replace it with upvalues rules. Also, some of the new pytests in #766 were included here. --------- Co-authored-by: rocky <[email protected]> Co-authored-by: R. Bernstein <[email protected]>
