bitbake-user-manual: Rewrite dependency dot file generation
The package-depends.dot and pn-depends.dot files are inaccurate, missing out key dependencies such those made via the [depends] flags. As such they can be misleading to the user. They mainly exist for historical reasons, coming from a time before we had task based execution. This commit removes the two dated file formats and replaces them with a recipe-depends.dot which is a flattened version of task-depends.dot. The old format files are removed if present so that the user can't get confused about why data might not match between files. The code is also rewritten to use 'with f: f.write()' syntax as is more commonly used now. Also update the docs to match the change. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

When you generate a dependency graph, BitBake writes three files
to the current working directory:
<itemizedlist>
- <listitem><para><emphasis><filename>recipe-depends.dot</filename>:</emphasis>
- Shows dependencies between recipes (a collapsed version of task-depends.dot).

- Shows dependencies between tasks. This matches bitbake's internal task execution list.
