Add lldb init file (#164344)
Adds an .lldbinit file to iOS app xcscheme.

Adding to scheme files can be error prone since a developer may be using
custom schemes (flavors). If we can't add it to the scheme, we print an
error without failing.

Since it is part of the scheme, it will be added to the project and will
be used on every run regardless of the device type/version. The Dart
side handles limiting to specific devices. If needed, we can alter the
.lldbinit file during `flutter assemble` to rewrite it since it doesn't
read the file until launch time (therefore it can be changed during
build time).

During `flutter assemble`, if the project doesn't have an LLDB Init File
set for any schemes, it'll throw an error if running in debug mode with
an iOS 18.4+ device.

Integration tests

These tests are not hermetic, and use the actual Flutter SDK. While they don't require actual devices, they run flutter_tester to test Dart VM and Flutter integration.

Use this command to run (from the flutter_tools directory):

../../bin/cache/dart-sdk/bin/dart run test test/integration.shard

You need to have downloaded the Dart SDK in your Flutter clone for this to work. Running ../../bin/flutter will automatically download it.

Coverage exclusion

These tests are expensive to run and do not give meaningful coverage information for the flutter tool (since they are black-box tests that run the tool as a subprocess, rather than being unit tests). For this reason, they are in a separate shard when running on continuous integration and are not run when calculating coverage.

Adding new test files

When adding a new test file make sure that it ends with _test.dart, or else it will not be run.
