ekf2: disable multi-EKF across mags by default (H7 & SITL) for now

- re-enable once the estimator selector respects configured mag
priority (at least initially) or is otherwise able to automatically
prefer an external mag over internal
 - for SITL disabled because the full matrix of esitmator instances
(IMUs X mags) was too many topics for logger currently
