Add support for VALUES query

[ayushdg]

Fixes #1013

Initial attempt at supporting the Values query.

Currently limited to creating the result on cpu dataframes only but eventually plan on extending to GPU frames via some common config.

Cool! Thanks for this addition Ayush. All the changes look sound to me

[ayushdg]

@charlesbluca since this is also one of those cases which would benefit from cpu/gpu handling does it make sense to followup on this once #1117 is complete?

[charlesbluca]

Yeah that makes sense - also okay with merging this in as is and iterating on it in my PR if we need VALUES implemented on CPU to unblock something
