[SPARK-14733] Allow custom timing control in microbenchmarks
## What changes were proposed in this pull request?
The current benchmark framework runs a code block for several iterations
and reports statistics. However there is no way to exclude per-iteration setup
time from the overall results. This PR adds a timer control object passed into
the closure that can be used for this purpose.
## How was this patch tested?
Existing benchmark code. Also see https://github.com/apache/spark/pull/12490
