Run PCApply manually if using ksp_type preonly -pc_type jacobi
This is to avoid an AllReduce call in KSPSolve_Preonly, which causes
significant slowdowns for lumped mass matrix solves.
See https://gitlab.com/petsc/petsc/-/merge_requests/8048 for more details
and a possible fix. This commit should be reverted once that MR moves
