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

This event was only called from one file (`flutter_command.dart`). With the previous implementation, we actually sent 2 events, one for the result of the `commandPath` and another containing the `maxRss` value from `ProcessInfo`.
I have consolidated this down to just one event and used a function to safely get the `maxRss` value, or return null when if there was an error getting that integer value
Fixes https://github.com/flutter/flutter/issues/134279.
Changes:
* Moves all tests of `--dart-define-from-file` behavior from `build_bundle_test.dart` and `assemble_test.dart` to `flutter_command_test.dart`.
* Deletes a duplicate test of malformed JSON detection behavior.
* Renames the `useDartDefineFromFileOption` method of `FlutterCommand` to `_usesDartDefineFromFileOption`. This 1) makes the name more consistent with the other `uses*Option` methods and 2) hides the method since it is not used outside of the file.
* Renames several tests to better articulate what is under test and what the expected result is.
* Adds a test for the case where a `.env` file with a malformed line is provided to `--dart-define-from-file`.
Resolves#128046.
Adds a services API that allows flutter app developers to write app code that determines `--flavor` the app was built with.
This is implemented by having the tool adding the value of `--flavor` to its list of dart environment declarations, which will be available to the app at run time. Specifically,`FLUTTER_APP_FLAVOR` is set. I chose this implementation for its simplicity. There is some precedent for this, but only for web ([example](cd2f3f5e78/packages/flutter_tools/lib/src/runner/flutter_command.dart (L1231))).
* Align `flutter pub get/upgrade/add/remove/downgrade`
* Add final . to command description
* Remove trailing whitespace
* Don't print message that command is being run
* Update expectations
* Use relative path
* Remove duplicated line
* Improve function dartdoc
This modifies the flutter update-packages and flutter update-packages --force-upgrade commands so that the many invocations of "dart pub get" in each repo project run in parallel instead of in series.
