sdk-manual, dev-manual: Applied SDK review edits.

* Removed the note box formatting for the cross-reference
   from the sdk-manual and dev-manual sections that
   talk about devtool.  The reference is now non-note
   form and goes to the ref-manual devtool quick ref.

 * Added devtool upgrade as a third item in the list that
   introduces methods to use devtool.

 * Fixed the working on the devtool finish step 5 for both
   the dev-manual and sdk-manual.

 * Renamed the new chapter that describes different projects
   you can use devtool on.  The focus is on using the SDK
   toolchain directly.

 * Scrubbed the entire sdk-manual for the term "toolchain
   installer" and replaced with "SDK installer".
