Add inpaint arguments and json format in .txt file

[Jibaku789]

Description

Issue:

While working and reproduce images generated using img2img inpaint tab, there are options that are not exported After try to generate the same images the options:

• inpaint_full_res_padding
• inpaint_full_res
• inpaint_mask_invert
• inpainting_mask_invert
• inpainting_fill

Also since i am adding more field to the generated .txt file, to improve the visibility of the options i added a new config parameter to export the file in json format

Solution:

• Add missing options to inpainting images generated
• Add new options to export .txt files in json format

Screenshots/videos:

UI functionality

Normal output

@AUTOMATIC1111 may you kindly review?

This PR has multiple unrelated things:

• adding missing infotext fields for img2img: this is welcome, but see below.
• adding an option to write infotext as json: I do not want multiple formats for infotext, so this change will not make it in.

Now, when adding infotext fields, you need both code to add them, and to read from them. You only have former.

The preferred way to add infotext fields it to use p.extra_generation_params dictionary, and not inside create_infotext function, but rather where they are used, i.e. in StableDiffusionProcessingImg2Img.__init__.

The other thing that needs to be done and isn't, is to add support for reading those fields into UI. See, for example, how mask_blur component does it.
