ProjectExplorer: Add BuildSystem class

Add a class to abstract out the BuildSystem from the Project.

Thie idea is to make a Project have-a BuildSystem, so that
it can stop being one.

The Projects in the different ProjectManagers will get much
simpler that way (and many will only consist of a constructor
with some setter calls) and handles all the interactions
between the rest of Qt Creator and the project.

The complex code to interact with the build systems is then
separate from that.
