Validate that runtime arrays aren't used as parameters

Browse Source 
Remove the logic around `arrayLength()` being passed anything but a member accessor. Runtime arrays types cannot be used for variables nor parameters.

Add validator logic and test for runtime array parameters.

Adjust the validator error message so it doesn't include the field / variable name. This read weird, and the same information is already provided by the source.
