[SPARK-14353] Dataset Time Window `window` API for R
## What changes were proposed in this pull request?
The `window` function was added to Dataset with [this
PR](https://github.com/apache/spark/pull/12008).
This PR adds the R API for this function.
With this PR, SQL, Java, and Scala will share the same APIs as in users can
use:
- `window(timeColumn, windowDuration)`
- `window(timeColumn, windowDuration, slideDuration)`
- `window(timeColumn, windowDuration, slideDuration, startTime)`
In Python and R, users can access all APIs above, but in addition they can
do
- In R:
`window(timeColumn, windowDuration, startTime=...)`
that is, they can provide the startTime without providing the
`slideDuration`. In this case, we will generate tumbling windows.
## How was this patch tested?
Unit tests + manual tests
