MdeModulePkg: move PlatformHasAcpiGuid from EmbeddedPkg

Given the agreement on the edk2-devel regarding the fact that the
notion whether or not a 'platform has ACPI' is a universal one, move
the PlatformHasAcpi GUID to MdeModulePkg.

+  EDKII Platform Has ACPI GUID
+
+  A NULL protocol instance with this GUID in the DXE protocol database, and/or
+  a NULL PPI with this GUID in the PPI database, implies that the platform
+  provides the operating system with an ACPI-based hardware description. Note
+  that this is not necessarily exclusive with different kinds of hardware
+  description (for example, a Device Tree-based one). A platform driver and/or
+  PEIM is supposed to produce a single instance of the protocol and/or PPI
+  (with NULL contents), if appropriate.
