commit 5f5c4b3e8a4e43f5ae8a114493084df4514b2939
Author: Mikhail Pozdnyakov <mikhail.pozdnyakov@intel.com>

Register CONTENT_SETTINGS_TYPE_SENSORS in ContentSettingsRegistry

Otherwise `navigator.permissions.revoke({ name: "accelerometer" })`
is causing crash.

I will verify them once the CL(https://chromium-review.googlesource.com/640931)landed in Chrome canary build.
Thanks.

Verified the fix on the latest Windows-10, Mac OS 10.12.6 and Linux Ubuntu 14.04 on chrome version: 62.0.3202.0. Observed no crash as such following the test steps mentioned in C#1. Hence adding the verified label.
