documentation: Added new appendix for customizing standard SDK

Fixes [YOCTO #8584]

This fix essentially had to document how to add the API
documentation to the standard SDK.  The fix required adding a
new appendix to the SDK manual on how to customize that
standard SDK.  I could not put just one topic in a new appendix
so I also added a sub-section on how to add indidual packages
to the standard SDK.

Other changes here were the introduction of a new file for the new
appendix, updated the mega-manual.xml file so that it would include
the new chapter when the MM was built.  Finally, I added some
cross-referencing to the new appendix from the TOOLCHAIN_HOST_TASK
and TOOLCHAIN_TARGET_TASK variables.  And a cross reference from the
distro features section on the api-documentation bullet.
