concepts-manual, dev-manual: Moved the virtual providers to dev-manual

This topic was deemed unfit for concepts so I moved it to the
dev-manual and rewrote it to be "Using Virtual Providers".

-                Prior to the build, if you know that several different recipes
-                provide the same functionality, you can use a virtual provider
-                (i.e. <filename>virtual/*</filename>) as a placeholder for the
-                actual provider.
-                The actual provider would be determined at build time.
-                In this case, you should add <filename>virtual/*</filename>
-                to
-                <ulink url='&YOCTO_DOCS_REF_URL;#var-DEPENDS'><filename>DEPENDS</filename></ulink>,
-                rather than listing the specified provider.
-                You would select the actual provider by setting the
-                <ulink url='&YOCTO_DOCS_REF_URL;#var-PREFERRED_PROVIDER'><filename>PREFERRED_PROVIDER</filename></ulink>
-                variable (i.e.
-                <filename>PREFERRED_PROVIDER_virtual/*</filename>)
-                in the build's configuration file (e.g.
-                <filename>poky/build/conf/local.conf</filename>).
-                <note>
-                    Any recipe that
-                    <ulink url='&YOCTO_DOCS_REF_URL;#var-PROVIDES'><filename>PROVIDES</filename></ulink>
-                    a <filename>virtual/*</filename> item that is ultimately
-                    not selected through
-                    <filename>PREFERRED_PROVIDER</filename> does not get built.
-                    Preventing these recipes from building is usually the
-                    desired behavior since this mechanism's purpose is to
-                    select between mutually exclusive alternative providers.
