Wolfgang Beyer b2da5bb358 Allow removal of entries from UMA enums ...

`recordEnumeratedHistogram()` needs both the actual bucket and the total
number of buckets. The total number of buckets was previously determined
by `Object.keys(someMap).length`. This prevented us from ever removing
keys from `someMap` since its length would change.
By explicitly adding a `LastValidEnumPosition` we can now safely remove
keys.
