Turn off verification for property trees

Turn off verification for property trees

As a part of staging the launch of property trees for the compositor
thread, first turn off verification entirely.  The next steps are to
locally fix problems when verification is on for the compositor thread,
and then turn it back on.

Another option would be separate main/compositor thread verification
flags, but that's more complicated.  Additionally, main thread
verification does very little except in a few cc unit tests, as
launching main thread property trees disabled most verification.

Depends on https://codereview.chromium.org/1136643006.

I should also mention that I explicitly did not turn off the
verify_property_trees setting in CalcDrawPropsMainInputs as several unit tests
depend on this (!!!) to trigger the building of property trees, which the unit
tests then check the values of (e.g.
https://code.google.com/p/chromium/codesearch#chromium/src/cc/trees/layer_tre...).

content/shell LGTM, as long as Blink's layout tests continue to pass.

I fixed those issues in https://codereview.chromium.org/1136643006 (which this
patch now depends on) and have updated this patch to turn off
verify_property_trees in all cases.

It should.  linux_blink_rel went green so I'll go ahead and land this.
