[ty] Always pass `NO_INSTANCE_FALLBACK` in `try_call_dunder_with_policy` (#18315) ## Summary The previous `try_call_dunder_with_policy` API was a bit of a footgun since you needed to pass `NO_INSTANCE_FALLBACK` in *addition* to other policies that you wanted for the member lookup. Implicit calls to dunder methods never access instance members though, so we can do this implicitly in `try_call_dunder_with_policy`. No functional changes.
