  [mlir][Presburger] NFC: return var index from IntegerRelation::addLocalFloorDiv (#153463)

addLocalFloorDiv currently returns void and requires the caller to know
that the newly added local variable is in a particular index. This
commit returns the index of the newly added variable so that callers
need not tie themselves to this implementation detail.

I found one relevant callsite demonstrating this and updated it. I am
using this API out of tree and wanted to make our out-of-tree code a bit
more resilient to upstream changes.
