Made TBB optional for hipstdpar tests

[NB4444]

Hipstdpar should work with and without TBB, so made a flag that as a default is OFF to make use or not of TBB.
Also set the rocprim path to hipstdpar and created a default value for another unrelated flag.

I have also added the commits from this #506 (comment) MR.

I'm encountering build errors when making the hipstdpar tests in Ubuntu (haven't tried other OSes but I assume they will be the same) when doing:

CXX=hipcc cmake -DBUILD_HIPSTDPAR_TEST=ON -DGPU_TARGETS=gfx942 ..
make -j

and so on. Even though we did not specify -DBUILD_HIPSTDPAR_TEST_WITH_TBB=ON, it looks like the hipstdpar tests still use TBB. Indeed, if manually add -ltbb to the build command, it builds properly.

According to https://stackoverflow.com/questions/67854770/i-do-not-use-tbb-but-i-get-linker-errors-related-to-tbb, it seems like when building with clang, it requires libtbb...

It seems to be a weird dependency, because it seems to be only needed to add the flag when TBB is installed. I tested it on the rocm/dev-ubuntu-24-04:latest which does not have any installation of TBB, which worked fine. After I installed libttb-dev I got the same compile error. So I changed the code to always add the flag when a TBB installation is found, this should fix this issue. If we keep getting more of these issues, it might be better to just disable these tests as a default or use something like try_compile in cmake to not let this hinder the other rocthrust tests.

Build failures are due to compiler bugs which will be resolved in upcoming newer builds. Otherwise, it looks good to me.
