ref-manual, dev-manual: Applied feedback to edit several classes

Fixes [YOCTO #8298]

Updated several classes with feedback from Jose Lamego of Intel.
The feedback fixed some class groupings so that previously isolated
classes could be bundled under common classes (e.g.
autotools*.bbclass).

I scrubbed the cross-references for cases where a particular
class became "undocumented."  The cross-references now point to
the bundled class entry in the ref-manual.
