The function to coalesce a fragmented capsule in memory.

@param BlockListBuffer Point to the buffer of Capsule Descriptor Variables.
@param MemoryResource Pointer to the buffer of memory resource descriptor.
@param MemoryBase Pointer to the base of a block of memory that we can walk
all over while trying to coalesce our buffers.

a coalesced capsule.

On output, this variable will contain the size of the

if the boot mode is not flash-update
if we could not find the capsule descriptors
@retval EFI_BUFFER_TOO_SMALL
if we could not coalesce the capsule in the memory
region provided to us
@retval EFI_SUCCESS if there's no capsule, or if we processed the
capsule successfully.
