Feat: Include Diffview context #1338
Description
Requested feature
Enable context info from diffview into lualine sections (winbar or others).
Motivation
Currently, diffview has its own mechanism (diffview-config-view.x.winbar_info) to provide context that is override by lualine.
It would be nice to enable a 'module'/'extension/ similar to 'diff' to integrate that on lualine winbar.
