[SPARK-24418][BUILD] Upgrade Scala to 2.11.12 and 2.12.6

## What changes were proposed in this pull request?

Scala is upgraded to `2.11.12` and `2.12.6`.

We used `loadFIles()` in `ILoop` as a hook to initialize the Spark before REPL sees any files in Scala `2.11.8`. However, it was a hack, and it was not intended to be a public API, so it was removed in Scala `2.11.12`.

From the discussion in Scala community, scala/bug#10913 , we can use `initializeSynchronous` to initialize Spark instead. This PR implements the Spark initialization there.

However, in Scala `2.11.12`'s `ILoop.scala`, in function `def startup()`, the first thing it calls is `printWelcome()`. As a result, Scala will call `printWelcome()` and `splash` before calling `initializeSynchronous`.

Thus, the Spark shell will allow users to type commends first, and then show the Spark UI URL. It's working, but it will change the Spark Shell interface as the following.

```scala
➜  apache-spark git:(scala-2.11.12) ✗ ./bin/spark-shell
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).

scala> Spark context Web UI available at http://192.168.1.169:4040
Spark context available as 'sc' (master = local[*], app id = local-1528180279528).
Spark session available as 'spark'.

scala>
```

It seems there is no easy way to inject the Spark initialization code in the proper place as Scala doesn't provide a hook. Maybe som-snytt can comment on this.

The following command is used to update the dep files.
```scala
./dev/test-dependencies.sh --replace-manifest
```
