refactoring

[light-and-ray]

While making this request I faced with problems and decided to include a small refactoring

• [Feature]: Can the interactive segmentation canvas be put in its own tab on auto11? #204

I've made these things:

1. Move all entry of scripts/sam.py into lib_segment_anything/sam.py except Script. It was needed to avoid ui tab duplication because script/api.py imports these entry and the module sam was duplicated
2. Move api.py into lib_segment_anything
3. Add special tab for segment anything. Disabled by default. In this mode txt2img script is hidden, and all img2img stuff goes into this tab via JS onUiLoaded callback, so all features work as usual img2img tab
4. In special tab mode there are few resizable columns for prettier look

Maybe it's a good idea to enable this tab by default. Because accordion is really to big and not very useful to be inside txt2img/img2img tab. Especially when dino box and mask dilation are shown
