[SPARK-9613] [CORE] Ban use of JavaConversions and migrate all existing uses to JavaConverters

Replace `JavaConversions` implicits with `JavaConverters`

Most occurrences I've seen so far are necessary conversions; a few have been avoidable. None are in critical code as far as I see, yet.

Closes #8033 from srowen/SPARK-9613.
