* remove MSVC support completely
* only find packages if they are needed

This avoids printing a lengthy and maybe surprising error message:

CMake Warning at examples/CMakeLists.txt:39 (find_package):
  By not providing "FindOpenCV.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "OpenCV", but
  CMake did not find one.

  Could not find a package configuration file provided by "OpenCV" with any
  of the following names:

    OpenCVConfig.cmake
    opencv-config.cmake

  Add the installation prefix of "OpenCV" to CMAKE_PREFIX_PATH or set
  "OpenCV_DIR" to a directory containing one of the above files.  If "OpenCV"
  provides a separate development package or SDK, be sure it has been
  installed.

HIP doesn't support CUDA 11.*

This reworks the previous adaptiv benchmarking.
Now, the number of iteration is determined on-the-fly instead of before-hand.
Also new cmd-line flags have been added to allow for greater control over the adaptive benchmarks.
The usage is similar to google benchmark.

Currently, it is not possible to use this approach for the preconditioner benchmark, as these do not update the runtime in each iteration.

this changes the preconditioner benchmark to time each preconditioner apply/generate individually, unifying the timing approach across all benchmarks.

- adds more documentation
- minor formatting
- made `status` private s.t. it is not part of the
  public interface of `IterationControl`

Now the `run_control` object also controls taking the timings. The user does not need to issue the timings by hand anymore. This allows to use increasingly larger intervals between two timings, unitl the benchmark run is finished.

Drawback: everything within the `ic.run()` loop gets timed, parts that should be exempt need to be moved outside of the loop.

Internally this uses a thin wrapper class for the `timer` object, which just skips the `tic/toc` calls, if the `run_control` object does not manage the timings. In that case, the timings have to be issued outside as before.

- clarify documentation
- add accessor to underlying timer
- formatting
- adds flag to choose repetitions growth factor

Since we added the DPCPP version information, we need to skip one
