dev-manual: Updated "Additional Implementation Details" section
Fixes [YOCTO #5517]
I added two package management system generic implementation
details to the section. This brings the section up to speed
as the definitive work on combining multiple versions of library
files into one image. We no longer have to refer the reader
to a separate wiki page.
