[SPARK-13635] [SQL] Enable LimitPushdown optimizer rule because we have whole-stage codegen for Limit
JIRA: https://issues.apache.org/jira/browse/SPARK-13635
## What changes were proposed in this pull request?
LimitPushdown optimizer rule has been disabled due to no whole-stage codegen for Limit. As we have whole-stage codegen for Limit now, we should enable it.
## How was this patch tested?
As we only re-enable LimitPushdown optimizer rule, no need to add new tests for it.

Closes #11483 from viirya/enable-limitpushdown.
