doc/mm: New documentation for memory performance

Platforms may provide system memory where some physical address ranges
perform differently than others, or is cached by the system on the
memory side.

Add documentation describing a high level overview of such systems and the
perforamnce and caching attributes the kernel provides for applications
wishing to query this information.
