Capsule Persistence Lib for PEI and DXE

This is an implementation of CapsulePersistenceLib which is used to persist capsules using the EFI partition.

It provides methods for:

• Persisting a capsule across reset
• Retrieving all currently persisted capsules and deleting them
• Retrieving a specific persisted capsule
• Deleting a specific persisted capsule

This library can be used without any sort of queue, by using a retrieve all method but, ideally, it should be paired with QueueLib.
