revset: inline spanset containment check (fix perf regression)
Calling a function is super expensive in python. We inline the trivial range
comparison to get back to more sensible performance on common revset operation.
Benchmark result below:

We can see this changeset gains back the regression for `and` operation on
spanset. We are still a bit slowerfor the `public()` and `draft()`. Predicates
not touched by this changeset.
