[DevTools] [CacheStorage] Live update cache storage list

Automatically adds/removes caches from the sidebar when they are created/deleted.
End to end plumbing to raise events when items are added and removed from individual caches is in place but not yet in use (will come in a later CL).

[DevTools] Throttle cache storage list live updates

Creating/deleting a large number of caches at once causes
noticeable slowdowns due to the large number of cache tree
nodes added. Added a time delay between list refreshes to
soften the performance hit.

Also switched to _loadCacheNames since refreshCacheNames
visually removes all caches in the list before re-adding
them.

 Issue 753421  has been merged into this issue.

Has making the "Refresh needed" indicator clickable been discussed?

I kept finding myself clicking it, then having to remember to click the ↻ button on the other side of the panel instead. I can file a new tracking bug if this idea hasn't already been discussed/rejected.

The refresh indicator is going to be removed here (https://chromium-review.googlesource.com/c/chromium/src/+/627716), and the entries will be live updated instead.
