[IGNITE-4818] .NET DayOfWeek does not work as a LINQ parameter

Description

IGNITE-4359 added support for DateTime.DayOfWeek, but it can't be used in Where clause:

var res = persons.AsCacheQueryable().Where(x => x.Value.BirthDay.DayOfWeek == DayOfWeek.Monday);

This fails because DayOfWeek.Monday is written as a serializable enum.

Workaround is to cast to an int:

var res = persons.AsCacheQueryable().Where(x => (int)x.Value.BirthDay.DayOfWeek == (int)DayOfWeek.Monday);
