[SPARK-24785] [SHELL] Making sure REPL prints Spark UI info and then
Welcome message
## What changes were proposed in this pull request?
After https://github.com/apache/spark/pull/21495 the welcome message is
printed first, and then Scala prompt will be shown before the Spark UI info is
printed.
Although it's a minor issue, but visually, it doesn't look as nice as the
existing behavior. This PR intends to fix it by duplicating the Scala `process`
code to arrange the printing order. However, one variable is private, so
reflection has to be used which is not desirable.
We can use this PR to brainstorm how to handle it properly and how Scala
can change their APIs to fit our need.
