doc: Change invokeMethod() comments to work with clang

There were four dummy declarations for struct QMetaObject that were
needed by old qdoc to allow documentation of some very complicated
function signatures that old qdoc could not parse. clangqdoc can now
parse these signatures, but, unfortunately, old qdoc is still used to
parse \fn commands in .cpp and .qdoc files, so the dummy declarations
are still needed in struct QMetaObject. However, clangqdoc now
sees that two of the four dummy declarations are actually duplicates
of the other two, and then old qdoc complains when it can't find all
four of the function nodes, when it parses the four \fn commands.
This update removes the duplicate dummy declarations and the two
redundant \fn comments. The remaining two \fn comments are
updated accordingly.

This change also moves a couple of qdoc comments so they are located
with the function definitions that they are documenting.
