Generated.xcconfig is only required at build time for iOS apps. In the
flutter create project template and example apps, Generated.xcconfig was
previously marked as a resource to be bundled into the built app.

This reverts commit 59bb2dba.

Uses the `version` property from the `pubspec.yaml` file to set the corresponding fields in the `local.properties` file respectively in the `Generated.xcconfig` file.

The `--build-name` and `--build-number` options have changed. Now they trump the `version` property from the `pubspec.yaml` file.

If the `version` property is not set and the  `--build-name` and `--build-number` options are not provided, the build command will not change the `local.properties` / `Generated.xcconfig` file.

This reverts commit 0f557e72.

This reverts commit dac1baf4.

Eliminates the restrictions to build in arm64 mode only in iOS project
templates created by flutter create.

This reverts commit c64ace84.

Dart is migrating to .dart_tool/ as the location for cached artifacts
and other temporary files generated by tooling in the SDK. As part of
this, pub will be migrating from .pub to .dart_tool/pub.

In future, this path will also be used for other tooling, such as package:build.

* update the IntelliJ metedata templates

* fix test expectation

These URLs all automatically redirect HTTP to HTTPS so makes sense to point users at the secure versions.
