polishing.

thanks to @Pribec for the suggestions

Kokkos - Limit excess synchronization on MI300A

use array notation (=vectorize)

COO: better error handling when COO indices are out of range

Reported by: Davi Yan@Discord

give intent = (in,out,inout) and mark as pure

regular do without line number

petscerror.h: iwyu export semi-private header

petscerror.h cannot be included directly unless petscsys.h has already
been included (and that unconditionally includes petscerror.h). This
updates docs

petscerror.h: iwyu export semi-private header

petscerror.h cannot be included directly unless petscsys.h has already
been included (and that unconditionally includes petscerror.h). This
updates docs and uses IWYU pragma export so IDEs (clangd) will
automatically include the correct header when you use things like
SETERRQ that appear petscerror.h.
