[M103 Merge][ntp] Apply special case handling for pride month GWS themes

This CL introduces the following special case treatments for pride
month Google Web Store themes:

  1. Removal of the scrim which darkens custom backgrounds
  2. Forced dark foreground colors for the Google logo and OGB

An explicit list of extension ids for the GWS themes that participate
in the above changes is maintained. This ensures the new behavior is
applied only to the specific GWS pride month themes targeted by UX.
Other themes will be unaffected by this change.

This is a short term fix intended to unblock the launch of these
pride month themes slated for June. Work on a longer term and more
comprehensive fix will follow quickly.

The themes shown below are not targeted by this CL but
demonstrate how these changes affect opted-in themes.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
