suite-sparse: fix issues with tbb (#28054)
* suite-sparse: Fix check for +/- tbb variant

Changed
'tbb' in spec
to
'+tbb' in spec

The former would configure suite-sparse to use tbb if any dependency
package (e.g. intel-oneapi-mkl) depends on tbb, even if
suite-sparse~tbb was specified.

* suite-sparse: conflict when trying to use 2021.x versions of tbb

See https://github.com/DrTimothyAldenDavis/SuiteSparse/issues/72

suite-sparse depends on task_schedule_init to control the number
of threads when e.g. interfacing with MATLAB.  However, Intel
dropped task_schedule_init in the 2021.x releases of TBB (it has
been deprecated since TBB 4.3.5).

We just raise a spack conflict when using tbb @2021.x and +tbb

Because tbb is a virtual package and is not versioned, I have
instead checked for either intel-oneapi-tbb@2021: or
intel-tbb@2021:, not the most elegant but should do the job
