[PATCH v3 1/6] SecurityPkg/SecurityPkg.dec: Move PcdCpuRngSupportedAlgorithm to MdePkg

["PierreGondois" <pierre.gondois@arm.com>]

From: Pierre Gondois <pierre.gondois@arm.com>

In order to use PcdCpuRngSupportedAlgorithm in the MdePkg in a
following patch and to avoid making the MdePkg dependent on another
package, move PcdCpuRngSupportedAlgorithm to the MdePkg.

As the Pcd is only used for AARCH64, place it in an AARCH64
specific sections.
