[SPARK-21608][SPARK-9221][SQL] Window rangeBetween() API should allow literal boundary

## What changes were proposed in this pull request?

Window rangeBetween() API should allow literal boundary, that means, the window range frame can calculate frame of double/date/timestamp.

Example of the use case can be:
```
SELECT
	val_timestamp,
	cate,
	avg(val_timestamp) OVER(PARTITION BY cate ORDER BY val_timestamp RANGE BETWEEN CURRENT ROW AND interval 23 days 4 hours FOLLOWING)
FROM testData
```

This PR refactors the Window `rangeBetween` and `rowsBetween` API, while the legacy user code should still be valid.

## How was this patch tested?

Add new test cases both in `DataFrameWindowFunctionsSuite` and in `window.sql`.
