Revert of Handle pointer-events: none in browser process hittesting.

Revert of Handle pointer-events: none in browser process hittesting. (patchset #23 id:460001 of https://codereview.chromium.org/1489913003/ )

Reason for revert:
Led to a large spike in renderer crashes in https://crbug.com/582149.  There's a fix in review (https://codereview.chromium.org/1648113002/) but it probably won't land in time for the next canary.
