Description

Move upscaler script in extras under input accordion. It's opened and enabled by default

Why I've made this:

• Upscaler 2 dropdown was at the same level with GFPGAN accordion
• Scale by / Scale to tabs section looked detached form the other options. I often loose it from my view
• to unify visual with other scripts

I've swapped scale row and upscalers rows for 2 reasons:

• Move "heavier" element to the bottom
• Repeat pattern from Hires. fix InputAccordion where Upscaler dropdown is upper then scale sliders

It's opened and enabled by default because:

• it's main feature of extras tab
• it preserves the previous behavior
• if user hasn't overridden default upscaler, they can not close and disable it because of None default upscalers. (The minimal number of clicks)

I've chosen InputAccordion to allow user change default upscaler, and simple disable upscaling script if they doesn't want to use it
