Overhaul of flutter drive in order to deliver a better experience, namely:
* flutter run and flutter drive now share more flags, so code paths that were previously only testable on run are now testable on drive.
* Removes web-initialize-platform as this is no longer used
* flutter drive correctly sets up a logger that shows native exceptions, by connecting to the vm service.
* VM service connection now provides access to memory info without launching devtools (only for debug/profile mode)
Web changes
* Passes on the one test in the repo, otherwise the webdriver code has been isolated as much as possible
Additional NNBD related bug fixes:
No longer passes --enable-experiment to the test script. (FYI @blasten ). earlier we might have assumed that the flutter gallery benchmarks would be migrated along side the app and flutter driver, but only the app under test needs to be migrated. The test scripts should never be run with the experiment.

[flutter tools] Add a DelegatingLogger class
Move most of `DelegateLogger` `from test/src/testbed.dart` to
`lib/src/base/logger.dart` to better formalize the common practice of
chaining `Logger`s together. I renamed the class since it isn't
itself the delegate and to better match the `Delegating...` classes
from `package:collection`.
Additionally, add a freestanding `asLogger<T>` function to "cast" a
`Logger` into a matching delegate if possible. This will allow
`Logger` chains to be ordered a *bit* more freely (e.g.
`NotifyingLogger` and `AppRunLogger` will no longer required to be
at the end of the chain, an unwritten rule that has led to breakage in
google3). Chain order still matters since lack of virtual dispatch
means that parent `Logger`s can never invoke child methods, however.
I made `asLogger<T>` a freestanding function because I didn't want to
make it part of the `Logger` interface (and I thought that making it
an extension method might be weird).
Bonus cleanup:
There no longer appears to be a way to construct an `AppRunLogger`
with a null parent, so remove all of code paths for that case and
make the `parent` construction parameter required.
Flutter logs should not attempt to filter the device list based on the current project, because it does not require a current project. Also fix disabled polling test

If a file scheme and one or more roots is provided, fall back to this mapping before the direct file path if the file path cannot be turned into a package URI.
Use URI representation so that the transformation is resilient to the org-dartlang-app scheme used by the web builds.

To support #61407 , the tool needs to check if a single widget reload is feasible, and then conditionally perform a fast reassemble.
To accomplish this, the FlutterDevice class will have a WidgetCache injected. This will eventually contain the logic for parsing the invalidated dart script. Concurrent with the devFS update, the widget cache will be updated/checked if a single widget reload is feasible. If so, an expression evaluation with the target type is performed and the success is communicated through the devFS result. An integration test which demonstrates that this works is already present in https://github.com/flutter/flutter/blob/master/packages/flutter_tools/test/integration.shard/hot_reload_test.dart#L86
Finally, when actually performing the reassemble the tool simply checks if this flag has been set and calls the alternative reassemble method.
Cleanups:
Remove modules, as this is unused now.
The global packages path could cause tests to fail when it would be overriden to unexpected (in test setup) values. Remove most usage and make it a configuration on buildInfo, along with most other build information. Cleanup the asset builder to require the .packages path and the resident runners to no longer require it, since they already have the information in build_info.
It needs to stick around for the fuchsia deps we do not control.
Filled #60232 for remaining work.
Refactors KernelCompiler and ResidentCompiler to no longer use globals (except as a fallback for g3 migration). Improves the compilation error when running flutter test on a package without a flutter_test dependency.
Updates machine mode to output trace text to stderr
instead of restricting profile/release mode based on whether the tool thinks the device is an emulator, restrict based on the device target architecture and the requested build mode. Notably, this enables release mode on x86_64 Android emulators, but not x86 emulators since we do not support that as an AOT target.
This does not add release mode support for simulators, since this requires us to build and upload artifacts for simulator/x86_64
Make it possible for all FlutterCommands to be global free, by moving instantiation to inside the Zone context. Additionally, provide VerboseLogger and NotifyLogger (daemon) at the top level and remove from command-specific overrides.
This allows removing a work around where web devices needed to look up directly from the context in non-test code.
Technically the output preferences are still zone injected, but these will be moved soon as they were not being used correctly by the top level command (the injection comes after ArgParser reads the overflow values, causing numerous wrap issues)
