Plex: More work adding in CEED backend
- Add DMPlexGetUseCeed() and DMPlexSetUseCeed()
- Need to propagate useCeed flag
- When using CEED, make tensor order the default, but shut it off for matrix in

Plex: More work adding in CEED backend
- Add DMPlexGetUseCeed() and DMPlexSetUseCeed()
- Need to propagate useCeed flag
- When using CEED, make tensor order the default, but shut it off for matrix insertion since this is still done by Plex kernels
- DMPlexMatSetClosureGeneral() now takes flag for closure permutation
- Add DMPlexMatSetClosure_Internal() which takes flag for closure permutation
- Add DMPlexVecGetClosure_Internal() with flag to turn off closure permutation - Turn off closure permutation in L2 diff calculation
- Add DMUseTensorOrder()
- Add DMPlexSNESComputeResidualCEED() - Cleanup SNES ex13 - Do not give CEED negative offsets

Delete unused code

Add static to internal functions

Profiling: Improve !defined(PETSC_USE_LOG) #defines

- If we cast macro arguments to void, we can avoid unused errors that have
forced lots of conditionally included code like this:

```c
#if def

Profiling: Improve !defined(PETSC_USE_LOG) #defines

- If we cast macro arguments to void, we can avoid unused errors that have
forced lots of conditionally included code like this:

```c
#if defined(PETSC_USE_LOG)
PetscLogEvent event;
#endif
```

- Having global counters like petsc_TotalFlops externed event
if !PetscDefined(USE_LOG) helps to remove a lot of needless
`#ifdef`s around code that can instead be placed in
`if (PetscDefined(USE_LOG)) {}` blocks.
