Splits support for using tbb (oneTBB now) between OS's when using
std::execution::par

It appears TBB support seems to wane in earlier versions of g++ in CentOS and
other OS's still require testing/containers to verify builds.

The MIGraphX shim should just operate as normal with copy_if and sort() calls
if TBB support isn't functional for the current OS/g++ version

Also moved the TBB dependency from install_preqs to Ubuntu Docker. Shouldn't breka
other dockers if support isn't added
