Make smart actions icon to respect dark theme setting

Problem:
The context from getPackageContext() does not have the theme set.

Solution:
Use the SystemUI theme to inflate the icon.
And we probably want to have a unified theme for all action chips anyway.

Test: Send myself a message "Code 12345", Verify that the
      icon works in both light and dark theme.
Test: Send myself a message "www.android.com", verify that the
      app icon is shown properly in both light and dark theme
