Clarify permission "HasAccess" behavior (#30585)

Browse Source 
Follow #30495

"HasAccess" behavior wasn't clear, to make it clear:

* Use a new name `HasAnyUnitAccess`, it will be easier to review related
code and permission problems.
* Separate everyone access mode to a separate field, then all calls to
HasAccess are reverted to old behavior before #30495.
* Add new tests.
