DVE: Function binding check for protected interfaces

If a function in IV is bound and has a protected/unprotected interface, the connected other function has to be in the same partition in DV

• During binding creation
• Automatically add "linked" functions when being bound
• Disable function unbinding for "linked" functions
• Check during load/check
• Sync DV when interface kind is changed to protected (how/when)? Use function binding consistency check ( #641 (closed) )
