Removing the Process() API and removing the parameters from the constructor will allow cmGeneratorExpressions to be cached and evaluated with multiple configs for example, such as when evaluating target properties. This requires the creation of a new compiled representation of cmGeneratorExpression. The cmListFileBacktrace remains in the constructor so that we can record where a particular generator expression appeared in the CMakeLists file.
