dev-manual, ref-manual: Re-wrote QEMU section.

Fixes [YOCTO #11630]

I converted the QEMU section to a procedure.  Also took the
tips section and created individual sections from that.

Cleaned up some areas in the QEMU conceptual section in the
ref-manual

         The Yocto Project uses an implementation of the Quick EMUlator (QEMU)

+        Within the context of the Yocto Project, QEMU is an
+        emulator and virtualization machine that allows you to run a complete
+        image you have built using the Yocto Project as just another task
+        on your build system.
+        QEMU is useful for running and testing images and applications on
+        supported Yocto Project architectures without having actual hardware.
+        Among other things, the Yocto Project uses QEMU to run automated
+        Quality Assurance (QA) tests on final images shipped with each
+        release.
         <note>
             This implementation is not the same as QEMU in general.
