This CL changes GetHeapSpaceStatistics api to return SizeOfObjects()

Revert of deprecate non-phantom weak callbacks (patchset #1 id:1 of https://codereview.chromium.org/1103173002/)

Reason for revert:
[Sheriff] Fails compilation on chromium android:
http://build.chromium.org/p/client.v8/builders/Android%20Builder/builds/4131

Is the chromium version our builder used maybe too old (it uses lkcr)? In that case please reland as soon as it's up-to-date.

Along the way, fix a corner case in WeakFixedArray, which can now be empty after
the recently introduced compaction support.
