Merge branch 'barry/2025-09-04/deprecate-mpiu-bool' into 'main'

Deprecate MPIU_BOOL which used to be for PETSc's enum Bool but now is just MPI_C_BOOL

See merge request petsc/petsc!8691

Merge branch 'stefanozampini/submat-zerorows' into 'main'

implement ZeroRowsLocal and ZeroRowsColumnsLocal for local references

Deprecate MPIU_BOOL which used to be for PETSc' enum Bool but now is just MPI_C_BOOL so no longer needs its own name

the etags parse got confused by the text Function cxxxx() in a comment in a CU file so remove it

Gather CUDA lib includes in petscdevice_cuda.h + disable cuSPARSE warnings using DISABLE_CUSPARSE_DEPRECATED

Defining DISABLE_CUSPARSE_DEPRECATED is Nvidia's recommended way of disabling cuSPARSE warnings
This avoids requiring -Wdeprecated-declarations - that can mask other (non-cuSPARSE) warnings

distinguish Boolean and Integer

MPI_Comm_get_attr has PetscMPIInt as flag argument, not PetscBool. Name
this flag "iflg" (was used somewhere already).
Use MPI_LAND instead of MPI_BAND for logical operations instead of
MPI_MIN, MPI_MAX, and MPI_LAND.

Note: Most of the previous code was probably working as intended, I did
the changes when debugging error related to the use of standard C Bool and
kept them because it took me a while to understand that MPI has integer
flags and PETSc has Booleans. Using different names makes this clear,
but was and is not done consistently.
