Sean Owen 7aca0dd658 [SPARK-29296][BUILD][CORE] Remove use of .par to make 2.13 support easier; add scala-2.13 profile to enable pulling in par collections library separately, for the future ... ### What changes were proposed in this pull request? Scala 2.13 removes the parallel collections classes to a separate library, so first, this establishes a `scala-2.13` profile to bring it back, for future use. However the library enables use of `.par` implicit conversions via a new class that is not in 2.12, which makes cross-building hard. This implements a suggested workaround from https://github.com/scala/scala-parallel-collections/issues/22 to avoid `.par` entirely. ### Why are the changes needed? To compile for 2.13 and later to work with 2.13. ### Does this PR introduce any user-facing change? Should not, no. ### How was this patch tested? Existing tests.
