[storage] Add out of space events

Add per-device histogram tracking the amount of times we run out of
space on device, indicated by failures to extend the underlying volume.

Add histogram to track the effectiveness of the mitigation added in
fxbug.dev/88364 to attempt to recover more space before failing.

Bug: 89583
Bug: 89874
Test: Tested locally to ensure events were logged & recorded by Cobalt.
