[FEATURE] Date Literals In "IN" Operator

[ZackFra]

Describe the solution you'd like
When using date literals with the "IN" operator, this should successfully apply the date literal to it.

e.g.

Opportunity opp = new Opportunity(
  CloseDate = Gmt.today()
);
DML.doInsert(opp, true);
List<Opportunity> queriedOpportunities = Selector.query('SELECT Id FROM Opportunity WHERE CloseDate IN (TODAY, YESTERDAY, TOMORROW)');

Assert.areEqual(1, queriedOpportunities.size(), 'Expected 1 opportunity to be found');
