Is your feature request related to a problem? Please describe.
Issue #3014 adds basic support for CreateMap from two expressions. This issue is to extend support for multiple expressions e.g. select map(key1, value1, key2, value2) from foo.

Describe the solution you'd like
We either need to implement this in cuDF or in the plugin. We could concatenate the columns into a single pair of columns before calling cuDF.

Describe alternatives you've considered
N/A
