MdePkg: introduce OrderedCollectionLib library class

This library class provides a set of APIs to manage an ordered collection
of items:
- Init(),
- UnInit(),
- Insert(),
- Delete(),
- IsEmpty(),
- Next(),
- Prev(),
- Min(),
- Max(),
- Find(),
- UserStruct().

There are many ways to implement an ordered collection. Depending on the
frequency of the different actions, different internal implementations may
have different performance, memory overhead, or code size.

Developers can select the library instance for a platform or module in
their DSC files that meets the needs of that platform or module.
