Standardize method for excluding Degree and Deviation from certain attribute calculations

[NateLanza]

Degree and Deviation are treated as attributes but are special and need to be excluded from certain attribute computations, ie having menus to choose the visualization in their column. Some places use attr === 'Degree' && attr === 'Deviation', some use ['Degree', 'Deviation'].includes(attr), etc. All this should be standardized into a single function (probably provided by core) so that the implementation is consistent and other attribute names can easily be added to the list of special attributes if more special attributes are added.
