docs: Breaking User Manual into smaller chapters.

The BitBake User Manual currently exists as one large XML file.
This change begins to break out he content into smaller, chapters.
This change extracts the Introduction content into its own
user-manual-intro.xml file, following the way the Yocto Project
organizes its Documentation.  SImilarly, this change moves renames
the doc/manual directory to doc/user-manual.  This will allow for
new documentation to be added as required with function specific
naming.
