924060929 0a95ebf602 [feature](Nereids) Add scalar function code generator and some function trait (#12671 )

This pr did these things:
1. Change the nullable mode of 'from_unixtime' and 'parse_url' from DEPEND_ON_ARGUMENT to ALWAYS_NULLABLE, which nullable configuration was missing previously.
2. Add some new interfaces for origin NullableMode. This change inspired by the grammar of scala's mix-in trait, It help us to quickly understand the traits of function without read the lengthy procedural code and save the work to write some template code, like `class Substring extends ScalarFunction implements ImplicitCastInputTypes, PropagateNullable`. These are the interfaces:
   - PropagateNullable: equals to NullableMode.DEPEND_ON_ARGUMENT
   - AlwaysNullable: equals to NullableMode.ALWAYS_NULLABLE
   - AlwaysNotNullable: equals to NullableMode.ALWAYS_NOT_NULLABLE
   - others ComputeNullable: equals to NullableMode.CUSTOM
3. Add `GenerateScalarFunction` to generate nereids-style function code from legacy functions, but not actual generate any new function class yet, because the function's trait is not ready for use. I need add some traits for the legacy function's CompareMode and NonDeterministic, this thought is the same as ComputeNullable.
