MdeModulePkg/UefiBootManagerLib: Generate boot description for SD/eMMC

Browse Source 
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=620

Adds the support for SD/eMMC device path to show as a boot option.

The CID register content (returned from DiskInfo->Inquiry) seems do not
provide very useful/readable 'OEM/Application ID' and 'Product name'
field.

For SD devices, the OID is a 2-character ASCII string and the Product name
is a 5-character ASCII string.

For eMMC devices, the OID is an 8-bit binary number and the Product name
is a 6-character ASCII string.

These strings are relatively short and do not provide a very readable
description. Hence, this commit uses general 'SD (eMMC) Device' for the
boot option description.
