Support casting to/from Interval and Duration

[alamb]

Is your feature request related to a problem or challenge? Please describe what you are trying to do.
In DataFusion we are trying to add complete date/time support . IN addition to Interval types some of this arithmetic will also likely result in Durations (e.g. timestamp - timestamp -- see #3964)

DataType::Duration(TimeUnit::Second)
DataType::Duration(TimeUnit::Millisecond)
DataType::Duration(TimeUnit::Microsecond)
DataType::Duration(TimeUnit::NanoSecond)

DataType::Interval(IntervalUnit::YearMonth)
DataType::Interval(IntervalUnit::DayTime)
DataType::Interval(IntervalUnit::MonthDayNano)

However, there is no easy way currently to convert between Durations and Intervals

Describe the solution you'd like
Add support for casting durations to intervals to the cast kernel : https://github.com/apache/arrow-rs/blob/master/arrow-cast/src/cast.rs#L18-L36

The following casts should be always supported as they are lossless (DataType::Interval(IntervalUnit::MonthDayNano) has nanosecond precision)

• DataType::Duration(TimeUnit::Second) <--> DataType::Interval(IntervalUnit::MonthDayNano)
• DataType::Duration(TimeUnit::Millisecond) <--> DataType::Interval(IntervalUnit::MonthDayNano)
• DataType::Duration(TimeUnit::Microsecond) <--> DataType::Interval(IntervalUnit::MonthDayNano)
• DataType::Duration(TimeUnit::NanoSecond) <--> DataType::Interval(IntervalUnit::MonthDayNano)

I am not sure what other, if any, casts should be supported

Describe alternatives you've considered

Additional context

[tustvold]

as they are lossless

TBC, the duration should be converted into the nanoseconds portion of MonthDayNano, returning an error or null (depending on CastOptions::safe) in the event of overflow.

As a result of daylight savings time, it would be incorrect to assume a day has 24 hours.

I am not sure what other, if any, casts should be supported

Truncating casts to MonthDayTime might also be worthwhile

I am glad to pick this up.
