* Add new hook for setupHotReload and after updating devFS is complete

* Handle the case where updateDevFS failed

This adds avoid_dynamic_calls to the list of lints, and fixes all instances where it was violated.

Importantly, this lint is NOT turned on for flutter/packages/test, because those changes are happening in another PR: #84478

* [flutter_tools] Serve DevTools at app start

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

[flutter_tools] use initially parsed package config for language version, sound mode determination (#70323)

If no source files were changed by a hot reload, do not send the reload sources RPC. This slightly speeds up the no-op reloads and gives users a faster way to force a re-render.

[flutter_tools] eagerly set asset directory path, cache flutter views, simplify error handling (#68978)

Performs some small cleanup on the hot reload code path.

- Combines nested try/catch into single try catch, update on clause now that package:vm_service is used and Map does not need to be caught.
- Cache FlutterViews for the lifetime of the hot reload method handler
- Set asset directory path once during startup and remove conditional set during hot reload

* [flutter_tools] null safety mode is used for dill naming

* add bad test case

Remove "This is taking a long time" progress timeout and TimeoutConfiguration.

A change which sped up hot restart locally caused many of the devicelab measures to regress. I think this is because we do not measure when the isolate is actually "ready", so starting a reload or restart prematurely can cause time spent doing initialization to be registered as part of the reload operation.

A fix for this would be to have the framework include some sort of "initialization complete" event ... but it is not clear what the correct trigger would be. Perhaps after the first frame is successfully registered?

(9a3a0dc1 caused the benchmark regression - possibly since we spend less time syncing files now so we start the restart earlier)
