Subject: ref-manual: Added the build/tmp/work-shared directory.

Added a brief explanation of this temporary directory to the chapter
that presents the structure of the Source Directory.  The
explanation is based on Paul Eggleton's input.

(From yocto-docs rev: 688c36aec57bb283d03ffb7e1d9448563cb1496c)

+            For efficiency, the OpenEmbedded build system creates and uses
+            this directory to hold recipes that share a work directory with
+            other recipes.
