Move printing related stuff to the root printing project from the browser project. This simplifies further refactoring and eases understanding of the printing part of Chrome.
Also renamed win_printing_context to printing_context_win (correct naming convention) and added stub implementations for _linux and mac.
Now all but one file is compiling on all platforms.
TEST=none (no functional change).
BUG=none
