Add options to show icon in Android TV and run app as Android launcher

[0xafbf]

For some reason AndroidManifest.xml files are not being used when building an app for Android. There are multiple reasons to add things to that file, but even though there are some places that tell the files are merged, it seems that it is always generated.

The reasons I had to modify this file are:

• Add the intent category LEANBACK_LAUNCHER so it adds an icon to Android TV launchers.
• Add the intent categories HOME and DEFAULT so a godot app can be used as a launcher itself (useful for kiosk experiences).

What I did in the end was to add these as export options, so the AndroidManifest generator adds these when the specific options are selected in the Export window.

Fixes part of #76963
Edit: doesn't actually fix that issue, as the AndroidManifest.xml problem persists. but it fixes the problem that the issue OP had.

Thanks! Based on the discussion in the issue, it should remain open until a more general problem is addressed.
