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.

StdLib/LibC/Uefi/Devices/daShell.inf
  Make this library also satisfy the DevMedia library class.
StdLib/StdLib.inc
  Add a library class definition for DevMedia
