Add `commandHasTerminal` parameter + apple usage event + `sendException` events for `package:unified_analytics` (#138806)

Relates to tracker issue:
- https://github.com/flutter/flutter/issues/128251

This PR includes 3 major updates:
- Adding the `commandHasTerminal` parameter for `Event.flutterCommandResult`
  - In `packages/flutter_tools/lib/src/runner/flutter_command.dart`
- Adding the new event for `sendException` from package:usage to be `Event.exception` (this event can be used by all dash tools)
  - In `packages/flutter_tools/lib/runner.dart`
- Migrating the generic `UsageEvent` which was only used for Apple related workflows for iOS and macOS. I did an initial analysis in this [sheet](https://docs.google.com/spreadsheets/d/11KJLkHXFpECMX7tw-trNkYSr5MHDG15XNGv6TgLjfQs/edit?resourcekey=0-j4qdvsOEEg3wQW79YlY1-g#gid=0) to identify all the call sites
  - Found in several files, highlighted in the sheet above

* exclude xcworkspace that begins with a period

* fix if spacing, add comment

* add unit test for when no xcworkspace found

* update to use xcodeWorkspace, make it nullable and refactor

* check if hostAppRoot exists before trying to get xcworkspace

* use local variables to take advantage of type promotion

* only check if not null, don't need to check if exists

* readd exist check for migrate

* readd missing line at end of file
