flow_ebos: print statistics about failed time steps

Browse Source 
the performance summary at the end of a Norne run which are printed by
`flow_ebos` now looks like this on my machine:

```
Total time (seconds):         773.757
Solver time (seconds):        753.349
 Assembly time (seconds):     377.218 (Failed: 23.537; 6.23965%)
 Linear solve time (seconds): 352.022 (Failed: 23.2757; 6.61201%)
 Update time (seconds):       16.3658 (Failed: 1.13149; 6.91375%)
 Output write time (seconds): 22.5991
Overall Well Iterations:      870 (Failed: 35; 4.02299%)
Overall Linearizations:       2098 (Failed: 136; 6.48236%)
Overall Newton Iterations:    1756 (Failed: 136; 7.74487%)
Overall Linear Iterations:    26572 (Failed: 1786; 6.72136%)
```

for the flow_legacy family, nothing changes.
