This reverts commit 7cdc23b3e1bae2bc7bc2d1f34773eaa3629d4fcc.
The failure in the `native_assets_test` integration test on Windows was caused by the DevTools process not being shutdown by the `ColdRunner` when running the profile mode portion of the test. This resulted in the test being unable to clean up the project created by the test as DevTools was still holding onto a handle within the directory. This PR adds back the mistakenly removed DevTools shutdown logic in the `ColdRunner`.

This change reverts the following previous change:
This change is a major step towards moving away from shipping DDS via Pub.
The first component of this PR is the move away from importing package:dds to launch DDS. Instead, DDS is launched out of process using the `dart development-service` command shipped with the Dart SDK. This makes Flutter's handling of DDS consistent with the standalone Dart VM.
The second component of this PR is the initial work to prepare for the removal of instances of DevTools being served manually by the flutter_tool, instead relying on DDS to serve DevTools. This will be consistent with how the standalone Dart VM serves DevTools, tying the DevTools lifecycle to a live DDS instance. This will allow for the removal of much of the logic needed to properly manage the lifecycle of the DevTools server in a future PR. Also, by serving DevTools from DDS, users will no longer need to forward a secondary port in remote workflows as DevTools will be available on the DDS port.
There's two remaining circumstances that will prevent us from removing DevtoolsRunner completely:
- The daemon's `devtools.serve` endpoint
- `flutter drive`'s `--profile-memory` flag used for recording memory profiles
This PR also includes some refactoring around `DebuggingOptions` to reduce the number of debugging related arguments being passed as parameters adjacent to a `DebuggingOptions` instance.

In a ProxiedDevicePortForwarder, there might be a race condition where the local socket has been disconnected, but the remote end was still sending new data. In this case, avoid forwarding new data to the socket.
Also move the vm service discovery logic into platform-specific implementation of `Device`s. This is to avoid having platform-specific code in attach.dart.
A ProxiedDevice has two port forwarder, one to forward remote host port and another to forward remote device port. During an attach workflow, the port was forwarded by the latter. Update ProxiedDDS to make sure that it works in such case.
List of changes:
1. Optimizations in FileTransfer. a. Use `stream.forEach` instead of `await for`. b. Type cast `List<int>` to `Uint8List` instead of using `Uint8List.fromList` results in (presumably) fewer copy and faster execution. c. Iterate through `Uint8List` with regular for loop instead of for-in loop.
2. Precache the block hashes of a file, and reuse it on subsequent runs.
The daemon ignores all device discovery that is not a PollingDeviceDiscovery. Make ProxiedDevices a PollingDeviceDiscovery so that it can be used in flutter daemon.
Note that there is a TODO item added in the test, which I intend to attempt fixing in a subsequent PR.
