Add support for Android Themed Icons

[lucasnlm]

Describe the project you are working on

Android 13 introduces a new kind of customization: Themed Icons.
With it, it's possible to make the app's icons use the theme color.

Example:

• Godot already supports Adaptive Icons.

Describe the problem or limitation you are having in your project

Currently Godot doesn't support Themed Icons without create a custom project.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Godot could have a theme icon field in the Launcher Icons options.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

Basicly, Godot supports adaptive icons with the following XML:

<?xml version="1.0" encoding="utf-8"?>
<adaptive-icon xmlns:android="http://schemas.android.com/apk/res/android">
    <background android:drawable="@mipmap/icon_background"/>
    <foreground android:drawable="@mipmap/icon_foreground"/>
</adaptive-icon>

By adding one line, it will support themed icons (<monochrome android:drawable="@mipmap/icon_monochrome"/>:

<?xml version="1.0" encoding="utf-8"?>
<adaptive-icon xmlns:android="http://schemas.android.com/apk/res/android">
    <background android:drawable="@mipmap/icon_background"/>
    <foreground android:drawable="@mipmap/icon_foreground"/>
    <monochrome android:drawable="@mipmap/icon_monochrome"/>
</adaptive-icon>

If this enhancement will not be used often, can it be worked around with a few lines of script?

If not used, all we have to do is omit the <monochrome android:drawable="@mipmap/icon_monochrome"/> line and it will work as is today.

Is there a reason why this should be core and not an add-on in the asset library?

We already support Adaptive Icons and Themed Icons is part of it.
By adding this Godot will also to encourage the right Android customization support.
