Plex: Now meshes can be created automatically from the command line, and some more fixes
- Changed internal mesh creation functions to operate on a DM instead of
creating a new one so that they can happen with options
- Fixed coordinates in CreateCubeBoundary_Internal()
- Added DMPlexShape for prebuilt meshes
- Added DMPlexIsSimplex()
- Added DMPlexCreateCoordinateSpace()
- DMPlexDistributeCoordinates() should copy the coordinate
discretization
- DMPlexInterpolateFaces_Internal() should be careful to preserve the
lower bound when resetting the chart
- PetscSectionSetChart() should ignore entries that match the current
ones
- Added DMPolytopeTypeSimpleShape()
- Do not require an EGADS model for TetGen
- Detail ASCII viewer shows all labels
- Default viewer shows periodicity

Merge branch 'jczhang/fix-kokkos-complex' into 'main'

Use Kokkos::complex when available

See merge request petsc/petsc!3904

Initialize CUDA in ViennaclInit

This enables ViennaCL to use CUDA event timers when CUDA backend is available.

Remove WaitForHIP before PetscLogGpuTimeEnd

Remove unneeded WaitForCUDA()

Use GPU event timer instead of CPU timer

- Support CUDA and HIP
- Initialize CUDA event timers along with CUDA
- Update dev changes
- Package-specific includes should not be placed in public include

Vec: weaken constraints on the returned index in VecMax/Min with empty vecs

So that vec backends are free to return any negative index

HDF5: Improve timestepping.

* add PetscViewerHDF5{Push,Pop,Is}Timestepping to control timestepping mode

* add PetscViewerHDF5{Push,Pop,Is}Timestepping to control timestepping mode
* write timestepping attribute for datasets and check it on reading
* fail gracefully if trying to read non-timestepped dataset in timestepping mode and vice-versa (fix #425)
* rewrite src/vec/vec/tutorials/ex19.c to improve coverage for timestepping testing
