MdePkg: Add two PcdApi for Patch VOID* PCD set operation.

Browse Source 
Two new APIs LibPatchPcdSetPtrAndSize() and LibPatchPcdSetPtrAndSizeS()
are added to catch the size of the updated VOID* PCD value buffer, then
PcdGetSize() API can return the actual size.

Update three PcdLib instances to implement these two APIs.
