UI polish tasks

[hrydgard]

• Easier way to record frame dumps directly from within the app, so we don't need the wiki page.
  • Maybe even automatically zip up and e-mail?
• Clickable notifications - useful for the above, and maybe some other things Clickable notifications #19020
• Uninstalling homebrew should be on a background thread, just like installing. Currently, uninstalling Suicide Barbie freezes the UI for 20 seconds (!) on phones with scoped storage
• Reorganize system settings: Reorganize "System" settings - plans #16877. Carefully!
• Add support for DPI setting
  • Would help Android devices with low resolution scale UI poorly #12644
• Remote games tab Remote Games Tab #18317
• Async load of savestate screenshots Async texture load on Pause screen #18538
• Better descriptions for tex upscaler Improved descriptions plus some additions #17071
