[SPARK-14321][SQL] Reduce date format cost and string-to-date cost in date
functions
## What changes were proposed in this pull request?
The current implementations of `UnixTime` and `FromUnixTime` do not cache
their parser/formatter as much as they could. This PR resolved this issue.
This PR is a take over from https://github.com/apache/spark/pull/13522 and
further optimizes the re-use of the parser/formatter. It also fixes the
improves handling (catching the actual exception instead of `Throwable`). All
credits for this work should go to @rajeshbalamohan.
## How was this patch tested?
Current tests.
