Update LeakExpectaions to include pointerevent_releasepointercapture_onpointerup_mouse-manual.html

It seems like there is a timing issue with this layout test, so this CL adds it to the leak expectation file.

Revert "Revert "Revert "Revert "Refactor the leak detector""""

This reverts commit 3d6d22736d0bee98b414a683b74f817c8400aa90.

Reason for revert: The failing layout test has a timing issue and it is added to LeakExpectaions. So this "Refactor the leak detector" CL should be able to safely land now.
