StdLib: Produce DevMedia as a library class alternative to DevShell.

StdLib: Produce DevMedia as a library class alternative to DevShell.
AppPkg: Replace existing DevShell dependencies with DevMedia.

These patches will NOT cause existing code which uses DevShell to break.
During an interim period, either DevShell or DevMedia may be used.
In the future, DevShell will be removed from the code base.

During the interim, DevShell and DevMedia refer to the same library.
