Add multi-container USB settings UI for Crostini

Expand the guest_os_shared_usb_devices page to support container
selection. Extend this page to crostini_shared_usb_devices for
Crostini-specific behaviours.

When the crostini-multi-container flag is disabled, the UI remains the
same and the original behaviour is emulated by attaching devices only to
the "penguin" container. When the flag is enabled, the container
selection UI is shown.

Test: unit_tests + browser_tests + tested on DUT

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.
