==== Methods on `DefaultTask` and `ProjectLayout` replaced with `ObjectFactory`

Use `ObjectFactory.fileProperty()` instead of the following methods that are now removed:

- `DefaultTask.newInputFile()`
- `DefaultTask.newOutputFile()`
- `ProjectLayout.fileProperty()`

Use `ObjectFactory.directoryProperty()` instead of the following methods that are now removed:

- `DefaultTask.newInputDirectory()`
- `DefaultTask.newOutputDirectory()`
