Those repeated descriptions hurt, feels like these really should be an enum...

I think they're unavoidable though, since the main purpose of these property descriptions is to show up in an inspector tooltip:
Changing the values to an enum and moving the full descriptions to the enum would mean that you have to open the docs and navigate away from the importer to see the descriptions of what each item does. Oh well.

We have something that handles this in the inspector, but not in the import options, export options, project settings or editor settings yet.
Fixes godotengine/godot-proposals#11243
Depends on #98071
Alternative to #81803
Adds color channel remap options to ResourceImporterTexture. These settings are part of the processing pass of the import operation, and allow discarding/replacing/overwriting the color channels of an imported image.
The following options are provided for each channel:
The other processes (such as format optimization) happen after this one, which makes it possible to remove unneeded color channels (like alpha), and the following steps (like compression) will take that into account (for instance by compressing as DXT1 instead of DXT5).
