[Reland] Enable AutoResize for Constrained Web Dialogs for Mac.

[Reland] Enable AutoResize for Constrained Web Dialogs for Mac.

Currently only constrained web dialogs for views (Linux/Windows) are able to
autoresize. This change implements the option to pass in minimum and maximum
sizes and enabling autoresizing functionality for OSX.

This change adds two static functions for options on whether to create a
ConstrainedWindowsMac that autoresizes or is of fixed size.

The first two patches were reverted because of flaky tests on Mac 10.9.

Those patches can be found at:
1. https://codereview.chromium.org/1430023002
2. https://codereview.chromium.org/1446623003

After some investigation, we found that the failures are being caused by an occlusion notifications in cocoa, which is not expected in browser tests. This is currently mac-only. By disabling these notifications in browser tests, we see this patch passing on the swarming bots that were previously failing. See http://crbug/558585.

[Reland] Enable AutoResize for Constrained Web Dialogs for Mac.

This change adds two static functions for options on whether to create a
ConstrainedWindowsMac that autoresizes or is of fixed size.

The initial patch was reverted because of flaky tests in Mac 10.9. Upon further
investigation, the ConstrainedWebDialogBrowserTest tests were also flaky on
other Mac versions, such as 10.10. At the time, the test would fail once every
4-5,000 runs. After picking up this patch again, I was unable to repro the
failing test after ~20,000 runs.
