Work towards #39925

Currently flutter run will uninstall and reinstall if the initial install fails and the APK was previously installed. Allow drive to share this same logic by moving it into installApp and out of startApp.

This should reduce the occurrence of the error in the devicelab.

This failure has been happening for a while but was covered by the overly broad catch. Removing that revealed that newer intellij versions have a different plugins file. The tool still can't find the file, but it won't crash now

Fixes #67918

Just another nnbd conversion PR.

In case different powershell module is installed over the default name. Fixes #22896

For historical reasons, the flutter tool uploads dill files to paths based on the entrypoint URI. This isn't actually necessary, and the tool can use specific files : main.dart.incremental.dill for incremental dills, and main.dart.dill/main.dart.swap.dill for full dills. This allows hot restarting applications with an entrypoint outside of lib/ and simplifies the devFS code.

Fixes #63243

[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.

If the vm of an attached device rejects a hot reload, pretty print the reason. Suggest a hot restart so that users are aware that they do not have to detach and rebuild. Also resets the last compilation time, so a subsequent restart would still apply the last change. Adds an integration test for the const field removal.

Fixes #64027

The train command does nothing and was originally added to provide a no-output default for generating app-jit snapshots. The inject-plugins command is only for a repo-only analysis check, which is not necessary since we regenerate during pub get.

[flutter_tools] remove globals from IntelliJ validator, refactor tests to remove dependency on JAR (#67240)

Move the intellij validator to its own file, and split off the tests. Remove globals from each, and remove dependency on a real jar/filesystem by creating a minimal version of the manifest xml and setting it up in the memory file system.

Now that fast-start syncs assets by default, this isn't testing anything. Retire the test

Do not upload all assets on initial devFS sync. This should increase the reliability of the initial connection, even in the face of flaky devfs behavior, in addition to a moderate perf improvement.

Updates fast-start to build assets as part of the initial bundle
