ShellPkg/memmap: Dump memory map information for all memory types

The patch dumps memory map information for all memory types.
But to follow the SFO format of "memmap" defined in Shell 2.2 spec,
the patch doesn't dump the memory map information for OEM/OS
memory types. But it does include the OEM/OS memory in the total
size in SFO format.
