docs/qapidoc: process @foo into foo

Add support for the special QAPI doc syntax to process @references as
``preformatted text``. At the moment, there are no actual
cross-references for individual members, so there is nothing to link
against. For now, process it identically to how we did in the old
qapidoc system.
