Ensure attaching to an application with an existing DDS instance is not treated as a fatal error (#70847)

ensure that the terminal handler checks if the service protocol is enabled before calling debug toggle brightness. Also removes globals from TerminalHander and test cases.

Fixes #65477

The k toggle allows switching between canvaskit and html backend at runtime. unfortunately this causes hot restart to break, since the dart_sdk modules stores state at runtime. The recommendation will be to use cavaskit via dart-defines.

* Optionally invert oversized images

These tests will hit the real Cache, failing if the flutter root has been modified

Fixes #56194

Remove caching of FlutterView and poll forever if the list of flutter views is empty. Added test for missing release mode logic.

This reverts commit 209bdcb6.

Remove caching of FlutterView. Perhaps the FlutterView RPC might return an empty list if the VM is not quite up yet? We had some old logic to poll the flutter views RPC for up to 200ms. That doesn't seem like a great approach, so instead we could forgo it entirely and trust that either the views come up before the developer tries to interact, or we crash.
