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

We used to use zip to verify the integrity of downloaded zip archives, but we now use unzip. This removes the .zip method from OperatingSystemUtils.

Re-arrange the implementation of the devtools launcher so that google3 is not required to depend on any devtools packages. Also renames the build_runner folders to isolated to better clarify their intention.

This is no longer used, in favor of just attempting to unzip and handling the exception.

Last batch of test fixes for general shard.

* Move doctor into globals

* Fix tests

The `runZoned` method deprecates the `onError` parameter.
Invocations using that parameter must use `runZonedGuarded` instead.

This prepares Flutter for the deprecation. The same places need to be migrated to using
`runZonedGuarded` when the SDK change has been ported to Flutter.
Then the deprecated member will be removed in a follow-up CL when the most important
packages have been migrated.

* Reland: [flutter_tool] Where possible, catch only subtypes of Exception

* Add armv7f to getIOSArchForName
