ref-manual, mega-manual: Updates to the SDK Generation section

Fixes [YOCTO #2808]

I updated the figure to not call out the SDK environment setup
script as it is part of the .sh file.  The figure was placed
in the "figures" directory of the ref-manual and the
mega-manual.

Also, I removed the duplicated variable descriptions and referenced
these descriptions in the "Application Development SDK" section,
which is further down in the manual.  The descriptions have more
to do with where output is placed.

(From yocto-docs rev: 256bb1447b571299b57c657bf030d5b4f033fb5f)
