config: Add a --without-python option to build process
Add the ability to build libgem5 without embedded Python or the ability to configure with Python. This is a prelude to a patch to allow config.ini files to be loaded into libgem5 using only C++ which would make embedding gem5 within other simulation systems easier. This adds a few registration interfaces to things which cross between Python and C++. Namely: stats dumping and SimObject resolving
