[SPARK-13817][BUILD][SQL] Re-enable MiMA and removes object DataFrame
## What changes were proposed in this pull request?
PR #11443 temporarily disabled MiMA check, this PR re-enables it. One extra
change is that `object DataFrame` is also removed. The only purpose of
introducing `object DataFrame` was to use it as an internal factory for
creating `Dataset[Row]`. By removing this object, both `DataFrame` and
`DataFrame$` are entirely removed from the API, so that we can simply put a
`MissingClassProblem` filter in `MimaExcludes.scala` for most DataFrame API
changes.
## How was this patch tested?
Tested by MiMA check triggered by Jenkins.
