Feature Flag for Dialog Touch Bar Support

Dialog touch bar support is currently behind
the Browser Touch Bar flag. This needs to be
separated into a separate flag that's disabled
by default.

Revert "Feature Flag for Dialog Touch Bar Support"

This reverts commit 62e55ea7afd2d153e85e1540800a9eb0d5b079a6.

Reason for revert: Breaks ContentSettingBubbleControllerTest.TouchBar:
https://build.chromium.org/p/chromium.mac/builders/Mac10.12%20Tests/builds/3958

I suspect that the InitAndEnableFeature call in that test simply needs to be updated correspondingly, but reverting since I'm not certain and this should be easy to reland with a fix if so.
