CMake modularization: macros creation

First step of this process that only considers the idea of
encapsulate the diffrent CMake processes we currently have in all
our main CMakeLists.txt files.

This patch simply takes some sections of the existing cmake files
and move them to a macro file.

Additionally, a couple of macros were written twice in shiboken
and pyside, so now they are only once.
