Kokkos: make dual view sync_host() asynchronous by adding an execution space argument

sync_host() without the argument is synchronous (like cudaMemcpy D2H). With the argument,
it is asynchronous (like cudaMemcpyAsync D2H).

To make sure the host array contains valide data immediately after dualview.sync_host(),
we need to do exec.fence();

Prune some PetscViewer internals:

1. Make functions used only within a single TU static
2. Make private functions used only within PETSc either PETSC_INTERN or
PETSC_SINGLE_LIBRARY_INTERN

Vec: revise ex2k cosmetically

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.
