Merge branch 'barry/2023-10-25/rename-rules-doc' into 'main'

Rename rules.doc and rules.utils because GitLab treats the former as a MS Word document.

SELL-based SpMV

See merge request petsc/petsc!3428

Initial commit for porting SELL to GPU

- Add tiled SPMV and basic SpMVfor SeqSELL
- Tested in serial
- Offloadmask is used to determine when the matrix should be copied to GPU
- Use different slice

Initial commit for porting SELL to GPU

- Add tiled SPMV and basic SpMVfor SeqSELL
- Tested in serial
- Offloadmask is used to determine when the matrix should be copied to GPU
- Use different slice height for CUDA version
- By checking the nonzerostate, PETSc can decide if the whole matrix need to be copied or just the values need to be copied
- Make the convert function public so that the very slow MatConvert_Basic can be avoided sometimes. E.g. one can use a two-step convert method: AIJ->SELL,SELL->SELLCUDA instead of the direct convert AIJ->SELLCUDA
- Make the FLOPS count for SELL same as that for AIJCUSPARSE.
- MatDisAssemble is not needed.
- Change slice height from 32 to 16 for GPU
- To overlap communication with MatMult, VecScatterBegin() should be called before MatMult() for the diagonal part.
- SLICE_HEIGHT is defined to be 32 to match the warp size of GPU. For other cases, it is still 8.

More support for not needing to set PETSC_DIR yet build with PETSc, also...

See merge request petsc/petsc!2626

build: add more support for not needing to set PETSC_DIR yet build with PETSc, also support for GNU make to directly use "make test" instead of "make -f gmakefile.test"

Still needs -include ../petsc

build: add more support for not needing to set PETSC_DIR yet build with PETSc, also support for GNU make to directly use "make test" instead of "make -f gmakefile.test"

Still needs -include ../petscdir.mk in many of the makefiles
Still needs the link for ../petscdir.mk in many directories

GNUMakefile: call legacy makefile recursively instead of including it

GNUMakefile: promote default "all" target; "libs" builds libpetsc*

GNUMakefile: If gnumake < 4.2 prefer makefile wrapper interface over direct gmakefile interface to avoid the following warnings

gmakefile.test:92: arch-ci-linux-cxx-cmplx-pkgs-64idx/tests/testfiles: No such file or directory
gmakefile:67: arch-ci-linux-cxx-cmplx-pkgs-64idx/lib/petsc/conf/files: No such file or directory
