[opt](Nereids) perfer use datev2 / datetimev2 in date related functions ( #20224 )
...
1. update all date related functions' signatures order.
1.1. if return value need to be compute with time info, args with datetimev2 at the top of the list, followed by datev2, datetime and date
1.2. if return value need to be compute with only date info, args with datev2 at the top of list, followed by datetimev2, date and datetime
2. Priority for use datev2, if we must cast date to datev2 or datetime/datetimev2

[Feature](Nereids) add executable function to support fold constant for functions ( #18209 )
...
1. Add date-time functions for fold constant for Nereids.
This is the list of executable date-time function nereids supports up to now:
- now()
- now(int)
- current_timestamp()
- current_timestamp(int)
- localtime()
- localtimestamp()
- curdate()
- current_date()
- curtime()
- current_time()
- date_{add/sub}(),{years/months/days/hours/minutes/seconds}_{add/sub}()
- datediff()
- {date/datev2}()
- {year/quarter/month/day/hour/minute/second}()
- dayof{year/month/week}()
- date_format()
- date_trunc()
- from_days()
- last_day()
- to_monday()
- from_unixtime()
- unix_timestamp()
- utc_timestamp()
- to_date()
- to_days()
- str_to_date()
- makedate()
2. solved problem:
- enable datev2/datetimev2 default.
- refactor Nereids foldConstantOnFE and support fold nested expression.
- separate the executable into multi-files for easily-reading and adding new functions
