project: Use dicts to keep track of copyfiles and linkfiles

This avoids copying/linking the same file/link multiple times if a
copyfile/linkfile element with the same values has been specifed
multiple times. This can happen when including a common manifest that
uses an extend-project element that has a copyfile/linkfile element.

This uses dicts rather than sets to store the copyfiles and linkfiles to
make sure the order they are specified in the manifest is maintained.
For Python 3.7+, maintaining the order that keys are added to dicts is
guaranteed, and for Python 3.6 it happened to be true.

The _CopyFile class and the _LinkFile class are changed to inherit from
NamedTuple to be able to store them in dicts.
