[TF:XLA] Make the two functions for computing HLO buffer interference consistent. 

Consider only real uses of fusion parameters when computing buffer interference
using HloDataflowAnalysis.

This is a step in unifying our HLO dataflow framework
to a single source of truth and improves HloOrdering::LiveRangeStrictlyBefore
to match the behavior of BufferLiveness::live_range_strictly_before (which uses
TuplePointsToAnalysis)
