[CVC Storage][Android] Create CVC save prompt for server cards

When CVC is detected for an existing server card during checkout, the
users are offered a prompt to save the CVC.

Create a Message to show this prompt.

Mock: https://docs.google.com/presentation/d/1PFxt_RRBiTOzxNGxU-vrHxmpmdjQznwGJKjrJZYFb68/edit#slide=id.g2588a7d143e_0_2
Implementation (light): https://screenshot.googleplex.com/7kFaNhZV27wcgXW.png
Implementation (dark): https://screenshot.googleplex.com/6UouYBdvh6obCHN.png

Note:
1. This CL only creates the UI components. The interactions will be
added added in a follow-up change.
2. This Message UI will be reused for the local CVC save prompt.

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.
