portals4: use a single Memory Descriptor to cover all of memory #581

In days past, some implementations of Portals4 could not cover all of memory with a single Memory Descriptor so multiple large overlapping Memory Descriptors were created. Because none of the current implementations have this limitation (and no future implementations should either), this commit removes the overlapping Memory Descriptors code.

of memory with a single Memory Descriptor so multiple large
overlapping Memory Descriptors were created. Because none of the
current implementations have this limitation (and no future

Memory Descriptors code in the BTL, MTL and OSC components.
