MdePkg BootManagerPolicy.h: Define GUID for connecting storage devices. 

Some platforms require connecting storage media while booting to
network, or require enumerating storage protocols that were not initially
enumerated during BDS. This change adds a GUID to allow implementation
of boot manager's ConnectDeviceClass to connect storage media.

EFI_BOOT_SERVICES.ConnectController(). If the Boot Manager has policy
associated with connect all UEFI drivers this policy will be used.
If Class is EFI_BOOT_MANAGER_POLICY_STORAGE_GUID then the Boot Manager will
connect the protocols associated with the discoverable storage disks. This may include
EFI_BLOCK_IO_PROTOCOL, EFI_SIMPLE_FILE_SYSTEM_PROTOCOL, or other storage protocols
appropriate to the device. Some platforms may choose to restrict the connected
devices to exclude USB or other peripherals.
A platform can also define platform specific Class values as a properly generated
EFI_GUID would never conflict with this specification.
