python-utils-r1.eclass: Reorder implementations to semi-ascending order
Reorder the Python implementations to ascending version order, with CPython listed first and other implementations in descending preference. The previous ordering has been used for two reasons: 1. There were packages which supported Python 3.x or PyPy partially but their documentation builds or test functions required CPython 2.x. The specific ordering caused python_export_best (the predecessor of python_setup) to use CPython 2.x for those tasks. This is now replaced by explicit implementation restrictions in python_setup. 2. PyPy setup runs were usually slower than CPython, and CPython 3.x runs were often slower due to 2to3 calls. Combined with parallel build runs, this ordering caused slower builds to start earlier and sometimes resulted in more efficient use of threads. However, nowadays we no longer do parallel builds. Therefore, it seems reasonable to finally reorder the implementations into a more intuitive order.
