put ConflictsWith on blocks that changed from ExactlyOneOf to AtLeastOneOf

Original Author: @danawillow

compute: Added back ConflictsWith restrictions for ExactlyOneOf restrictions that were removed in v3.3.0 for `google_compute_firewall`, `google_compute_health_check`, and `google_compute_region_health_check`. This effectively changes an API-side failure that was only accessible in v3.3.0 to a plan-time one.

This effectively changes an API-side failure that was only accessible in v3.3.0 to a plan-time one.
