Introduction of ThemedIcon that appears to have two colors

[kosenda]

Overview

ThemedIcon is not applied, but I feel it should be. Also, if we introduced ThemedIcon as usual, it would look quite similar to the 2022 and 2023 app icons, so we thought it would be a good idea to do the following to differentiate them by making them look like they are composed of two different colors. （Creating a monochrome will not affect the display of the splash icon at startup）

1. Introduce ThemedIcon as we did last year.
2. Create a file named ic_launcher_monochrome.xml with a copy of ic_launcher_foreground.xml in a directory named drawable-v31.
3. Set ic_launcher_monochrome on monocrome of ic_launcher_round.xml and ic_launcher.xml
4. Set android:fillAlpha=“0.5” in one of two paths of ic_launcher_monochrome.xml to make one side figure translucent
