refactoring of QPrinterInfo

move QPrinterInfoPrivate to it's own header file;
rename qprinterinfo.qdoc to qprinterinfo.cpp to make it consistent with others;
squash the duplicated code into qprinterinfo.cpp;
avoid extra d_ptr assignments in the QPrinterInfo copying c-tor;
simplify the QPrinterInfo from QPrinter c-tor code;
fix styling and few method param names;
remove the `m_` prefix of QPrinterInfoPrivate's members (as they are members
of a private class anyway ;P)
remove the boilerplates
