Currently, the DXE page allocator does not ensure that guard page allocations stay within the bin that it is attempting to allocate within. As a result, S4 resume is jeopardized by bins expanding due to guard pages, either into other bins or out of bins. This is caught by a new assert in CoreGetMemoryMap() to ensure the bins are correct. This fixes this by changing the internal heap guard API to return the adjusted size and start address of a proposed allocation. The page allocator then can ensure that the adjusted allocation still fits within the bin it is attempting to allocate within; if not, it will search for another descriptor.
