emitKeyPathSubscriptOperands() uses the ArgEmitter to collect index arguments, which uses ResilienceExpansion::Minimal when lowering parameter types. For this reason, lowerKeyPathSubscriptIndexTypes() should also use ResilienceExpansion::Minimal when lowering parameter types. Otherwise, we crash in the SIL verifier due to a loadable vs address-only mismatch, if the index type is resilient. Fixes rdar://problem/144654366. Fixes https://github.com/swiftlang/swift/issues/79304.
