Do not trigger contextual typing when `array_literal_providers` flag is on but LTI flag is off
Do not trigger contextual typing when `array_literal_providers` flag is on but LTI flag is off

Summary:
When `array_literal_providers` is on and the array is has hint, we will run contextual typing, which is only designed to be run together with LTI. In this diff, I will do nothing when the array literal as hint but LTI flag is not on. This ensures that `array_literal_providers` flag can be independently turned on.
