This change make it easier to track the position of the scroll view without
having to worry about the position object changing out from under the
controller.
1. Add `PortScanner` abstraction so that we don't do actual port scanning
in tests.
2. Don't change the real `cwd` of the isolate during tests, as it affects
all tests, not just the current running test.

- [x] Add custom logic on MacOS to determine if Java is installed before invoking `java`.
- [x] Check JAVA_HOME, platform specific logic, and finally PATH to locate the `java` executable.
- [x] Improved doctor messages.

* Use snapshot's .d file as source inputs in Gradle build.
If we don't yet have a .d file (first build), fall back to using the
.dart files in the current directory. This enables us to detect changes
in dependent source files (Flutter framework, packages outside the
source directory, etc.), and re-generate the snapshots as needed.
Unfortunately, Gradle requires knowing the source files before executing
the task, and can't update them after building, so Gradle considers the
second build to be out-of-date (because it has more input files than the
first build). Sub-sequent builds have the correct dependency
information, and will be skipped if the source files haven't changed.
Also added a dependency on gen_snapshot. The snapshot ABI isn't stable,
so we need to re-generate the snapshots when we roll the Dart SDK
dependency.

It was resulting in weird situations where the tool would dump an
error message and stack but not quit, or would fail hard but then just
hang.
Instead, specifically catch errors you expect. As an example of this,
there's one error we expect from the DartDependencySetBuilder, so we
catch that one, turn it into a dedicated exception class, then in the
caller catch that specific exception.
* Revert "Eliminate CocoaPods install step (#8694)"
This reverts commit f4a13bc72b0d0a6f08592a24a61cc92f86e62061.
If the developer is relying on CocoaPods and hasn't done a pod install, we will do it for them. This is needed for a smooth native plugin experience, similar to what Gradle is doing on the Android side.
There's no hard dependency on CocoaPods. We only run pod install if the project uses CocoaPods, so developers are still free to use alternatives if they prefer (and if they don't want to use native plugins).
Fixes#8685Fixes#8657Fixes#8526
* Require CocoaPods 1.0.0 or newer.
And make sure we don't get a crash if running `pod install` fails.
* Address review feedback
If the developer is relying on CocoaPods and hasn't done a pod install,
they'll get a build failure indicating the issue.
This also avoids a hard dependency on CocoaPods in the tool and allows
developers to customize their Xcode steps to use alternatives such as
Carthage if they prefer.
