Reorganize files in repo, pull out build settings from pbxproj (#1140)

This is somewhat in prep of being able to make the project file generated, but also just organizes things into more concrete directory structures.

This pulls out _all_ of the build settings from the root level, and most from the target level, into xcconfigs.

The new directory structure looks like:

- Sources
  - App
    - (everything from HomeAssistant/)
  - WatchApp
  - Shared
  - MacBridge
  - Extensions
    - Intents
    - NotificationContent
    - NotificationService
    - Share
    - Today
    - Watch
    - Widgets
- Tests
  - App
  - UI
  - Shared

Somewhat intentionally, the file structure under these is not yet standardized/organized.

The project targets are now:

- App
- WatchApp
- Shared-iOS
- Shared-watchOS
- MacBridge
- Tests-App
- Tests-UI
- Tests-Shared
- Extension-Intents
- Extension-NotificationContent
- Extension-NotificationService
- Extension-Share
- Extension-Today
- Extension-Widget
- WatchExtension-Watch

This does not yet clean up resources vs. sources, nor does it handle some of the "it's in Sources/App but it's part of Shared" crossover directory issues.
