Added M69 and p2 since we should have this in M69.

This should be for the DV lock + EV string; aka all places that are currently green.

Omnibox UI Refresh: Update Secure chip color to gray for Refresh

When the Refresh flag is on, after this CL, even secure sites will
appear as gray.

Also to match the mocks, incognito mode icons have been recolored to
Google Gray 200 instead of 100 when Refresh flag is on.

Tested the issue on latest chrome version# 69.0.3446.0 using Mac 10.12.6, Ubuntu 14.04 and Windows 10 with steps mentioned below:
1) Launched chrome version and navigated to chrome://flags and enabled refresh flag
2) On NTP, navigated to secure site(for example google.com) and observed Secure chip turns to gray on Linux and Windows, but on Mac it remains same as green colour.

@Tommy C. Li: Please find the attached screencast of Linux and Mac and help us in confirming the fix on Mac OS.

Thanks!

On Mac Cocoa we expect it to remain Green.

Please confirm that on Mac Views it is Gray with these flags:

#views-browser-windows → Enabled
#top-chrome-md  → Refresh
#secondary-ui-md → Enabled
