Allow optional second argument denoting timezone for datetime extraction functions in the multi-stage engine

[yashmayya]

• The date time extract functions in Pinot like YEAR, DAY_OF_YEAR, DAY_OF_WEEK etc. support an optional second argument denoting the timezone for the timestamp (both the transform and scalar function implementations support this).
• However, we use the standard operator definitions from Calcite in the multi-stage engine that only support a single operand (the datetime type). This leads to errors like Invalid number of arguments to function 'DAYOFWEEK'. Was expecting 1 argument on attempting to use the function like DAYOFWEEK(ts, 'UTC').
• This patch fixes the issue by removing the standard operators from the operator table and instead defining our own custom operators with the appropriate operand type checkers (the return type inference is kept the same as the one from the standard operators).
