Bug Report: Query not normalized properly

[GuptaManan100]

Overview of the Issue

It was noticed that we aren't normalizing all the queries properly. Specifically for a query like select a, b from t group by 1, field(a,1,2,3) order by 1 asc, field(a,1,2,3), we should be converting all the literal values in the field function call to bind variables, but we aren't doing that.

Reproduction Steps

Start a vitess cluster and execute the query listed. See the query plans in vtgate dashboard.
