relaxInputConstraint

function relaxInputConstraint(
   kind, 
   input, 
   devices): 
  | undefined
  | InputDeviceConstraint;

Relax input constraints to enable looking up the device by deviceId as well as label as a fallback as a best effort to get a similar device when possible. If the the device is found we will use the exact constraint otherwise we will use the ideal.
