Fix PassArrays Properties panel.

Updating PassArrays proxy definition to use domains for setting up array
selections (rather than the now removed custom panel). This exposed a
bug in vtkSMInputArrayDomain where due to missing breaks in the switch
statement, the CellDataArrays domain ended up showing point data arrays
as well. Fixed that.
