More intuitive inpainting

Is your feature request related to a problem? Please describe. Currently inpainting is very difficult to use as is so please make it more availible.

Describe the solution you’d like User actions:

• Use any selection tool to select an area of the image to inpaint
• Call the inpainting plugin, which warns the user if there is no selection availible or layer is empty / non rasterized.

The following actions are done by the plugin:

• Fill the selected area with a solid color without antialiasing on a new (mask) layer;
• (if needed) Convert the mask layer to a format the inference module understands;
• Save image layer and mask layer as cache0.png / cache1.png;
• Send them to the inference module which saves its output as result.png or produces an intelligible error text (The inference module should fill only pixels corresponding to non-transparent mask-layer pixels leaving the rest transparent.);
• Replace the mask layer with result.png so the it will have only inpainted region;
• Delete cache and inference result files.

Additional context Currently if inpainting fails it does so silently without any intelligible error messages whatsoever, please fix it too.

this is the only documentation available for the time being https://github.com/GNOME/gimp/tree/master/devel-docs/GIMP3-plug-in-porting-guide

sorry but there is not much documentation available, the best way is to see other plugin files and see usage.
