fluids: Add turb spanstats test, change test option

- `-test` changed to `-test_type` enum to test different outputs

fluids: Use enum for turbulence statistics components

- Also change the filenames to be more specific
- Define num_comp_stats via TURB_NUM_COMPONENTS

fluids: Change turb_spanstats CL option names

- Options controlling the actual TSMonitor are under
`ts_monitor_turbulence_spanstats_*`
- `stats_enable` removed in favor of
`ts_monitor_turbulence

fluids: Change turb_spanstats CL option names

- Options controlling the actual TSMonitor are under
`ts_monitor_turbulence_spanstats_*`
- `stats_enable` removed in favor of
`ts_monitor_turbulence_spanstats_viewer` being the statistics switch
- Related objects excluding the viewer (such as the dm and ksp) get the
prefix `turbulence_spanstats`
- Change the `stats_test` related functions and variables to use the
`mms` nomenclature, since they're method of manufactured solutions.

fluids: Require spanstats collection when writing

- Otherwise, stats may be written to file with a timestep/solution time
associated with it that wasn't collected.

examples/fluids: fix stats after restart

* Switch from reweighted average to running sum of child stats
* Initialize sp_stats->prev_time after restart
* Use TS reason instead of extra flag
* Skip

* Initialize sp_stats->prev_time after restart
* Use TS reason instead of extra flag
* Skip redundant monitor call; monitors always get called after last step (converged or not)
* Close memory leak

fluids: Create UpdateBoundaryValues, fix statistics

- Statistics would fail when non-zero strong bcs were used due to Q_loc
not containing those values. Instead, use user->Q_loc and call
UpdateB

- Note this relies on the periodicity being isoperiodic rather than
topologicially periodic.

fluids: Use persistent viewer for statistics

- Use prefix 'stats_viewer'
- Particularly useful for setting `stats_viewer_cgns_batch_size`

- Effectively duplicate of TSMonitor_Statistics
