MdeModulePkg: Make HII configuration settings available to OS runtime
This feature is aimed to allow OS make use of the HII database during runtime. In this case, the contents of the HII Database is exported to a buffer. The pointer to the buffer is placed in the EFI System Configuration Table, where it can be retrieved by an OS application.
