Implement persistent caching for simplify_condition
Store the results of simplify_condition in a json cache file,
next to the pro2cmake.py script.
Dramatically speeds up re-conversion of projects.
The cache is cleared whenever the content of the
condition_simplifier.py file changes, effectively presuming that the
condition computing code has changed.
Sample times.
Initial corelib.pro conversion - 142.13 seconds.
Next re-conversion with hot cache - 1.17 seconds.
