concepts-manual: Added a section on "Layers"

The section briefly introduces layers but leaves the real
explanation to the section in the getting-started manual,
which this section references.

+            Layers are repositories that contain related sets of instructions
+            that tell the OpenEmbedded build system what to do.
+            You use different layers to logically separate information in your
+            build.
+            You can collaborate, share, and reuse layers.
+            The Layer Model simultaneously supports collaboration and
+            customization.
