adt-manual: delete obsolete ADT manual, and related content

Since the ADT manual has long been superseded by the SDK manual,
remove the entire adt-manual directory, and the references to it in
the two top-level files "conf.py" and "poky.yaml".

-Introduction
-************
-
-Welcome to the Yocto Project Application Developer's Guide. This manual
-provides information that lets you begin developing applications using
-the Yocto Project.
-
-The Yocto Project provides an application development environment based
-on an Application Development Toolkit (ADT) and the availability of
-stand-alone cross-development toolchains and other tools. This manual
-describes the ADT and how you can configure and install it, how to
-access and use the cross-development toolchains, how to customize the
-development packages installation, how to use command-line development
-for both Autotools-based and Makefile-based projects, and an
-introduction to the Eclipse IDE Yocto Plug-in.
-
-.. note::
-
-   The ADT is distribution-neutral and does not require the Yocto
-   Project reference distribution, which is called Poky. This manual,
-   however, uses examples that use the Poky distribution.
