feat(app-framework): Add support for global middlewares

[ChristophWurst]

Resolves: an idea I had in my mind for years

Summary

This allows apps to register middlewares that always register, not just for the app's own requests. Example: ChristophWurst/nextcloud_sentry#329 and a middleware that monitors the performance of other apps' controller methods.

TODO

• Finish perf(app-framework): Make app middleware registration even lazier #36298

Checklist

• Code is properly formatted
• Sign-off message is added to all commits
• Tests (unit, integration, api and/or acceptance) are included
• Screenshots before/after for front-end changes
• Documentation (manuals or wiki) has been updated or is not
  required
  • feat(dev-manual): Document global middleware registration documentation#9588
• Backports requested where applicable (ex: critical bugfixes)

Should also go into #34692 but can be very short/brief there and link to the docs you already wrote 👏🏼
