🛃 Allow TWA sites to theme the status bar color.

When on the verified origin in a Trusted Web Activity, the page's theme
color will be used for the status bar. Previously this was ignored and
the toolbar color provided by the client was used. The page's theme
color takes precedence over the toolbar color if provided.

This results in the following logic for the status bar color in TWAs:
- If on the verified origin:
  - If the page has a theme color, use that.
  - Otherwise if the client provided a toolbar color, use that.
  - Otherwise use Chrome's default.
- Otherwise, if not on the verified origin:
  - If the client provided a toolbar color, use that.
  - Otherwise use Chrome's default.
