[analytics] propagate env to sub-tools (#8976)

Follow-up from #8966 which introduced support for propagating the
standard JetBrains telemetry environment variables (`DASH__*` and
`FLUTTER_HOST`) via the `Analytics.updateEnvironment(commandLine)`
utility, this updates four additional spots where standalone processes
are spawned manually using the `GeneralCommandLine` class, ensuring
environment variables are propagated correctly in those contexts as
well.

Fixes: #8975

### Changes

#### 1. Device Daemon Spawning
(`src/io/flutter/run/daemon/DeviceDaemon.java`)
* **Modification**: Invoked `Analytics.updateEnvironment(result)` inside
the `toCommandLine()` helper before returning the `GeneralCommandLine`
instance. This ensures the background `flutter daemon` process runs with
propagated telemetry parameters.

#### 2. Bazel Test Execution
(`src/io/flutter/run/bazelTest/BazelTestFields.java`)
* **Modification**: Invoked `Analytics.updateEnvironment(commandLine)`
in the `getLaunchCommand(...)` method before returning the constructed
command line, allowing the Bazel test runner process to receive the
telemetry variables.

#### 3. Bazel Flutter Doctor Execution
(`src/io/flutter/actions/FlutterDoctorAction.java`)
* **Modification**: Invoked `Analytics.updateEnvironment(cmdLine)` in
`runWorkspaceFlutterDoctorScript(...)` before spawning the
workspace-specific doctor script.

#### 4. Bazel File Synchronization
(`src/io/flutter/run/FlutterReloadManager.java`)
* **Modification**: Invoked `Analytics.updateEnvironment(commandLine)`
in the `syncFiles()` helper to propagate the environment variables to
the Bazel file synchronization script during reload events.
