Detect changes to PBXResourcesBuildPhase during target build up-to-date checking

[lacasseio]

As a user building Xcode targets using Gradle, I want the Gradle tasks representing the Xcode targets using PBXResourcesBuildPhase to be out-of-date when its build specification change during an incremental build so I can have accurate feedback.

Tasks

Beta Give feedback

1. Detect changes to PBXBuildFile during build up-to-date checking #788
   a:enhancement in:xcode-build-adapter +2

Acceptance Criteria

• Changes to the build phase name don't cause the task to be out-of-date. The name of a build phase is only an organizational tool and does not impact the build itself. (Cannot change the build phase name via IDE)
• Any changes to files, e.g. adding new items or removing existing items. Ordering change should have no effect.(We decided against ignoring ordering.)
• Any change to the content of the files/directories represented by files.
