Subject: tbb: Split into tbb_2020_3 and tbb_2021_8

This is based on PR #214762.

For the new release 2021.8, see
https://www.intel.com/content/www/us/en/developer/articles/release-notes/intel-oneapi-threading-building-blocks-release-notes.html
https://github.com/oneapi-src/oneTBB/releases/tag/v2021.5.0
https://github.com/oneapi-src/oneTBB/releases/tag/v2021.6.0
https://github.com/oneapi-src/oneTBB/releases/tag/v2021.7.0

Due to the significant breakage due to the update to TBB 2021.8, instead
split the tbb package into tbb_2020_3 and tbb_2021_8, with the default
tbb aliased to tbb_2020_3 in order to minimize breakage.

Also fixed build issues and improved code.

+      Intel Threading Building Blocks offers a rich and complete approach to

+      take advantage of multi-core processor performance without having to be a
+      threading expert. Intel TBB is not just a threads-replacement library. It
+      represents a higher-level, task-based parallelism that abstracts platform
+      details and threading mechanisms for scalability and performance.
