tools/memory-model: Clarify the origin/scope of the tool name

Ingo pointed out that:

  "The "memory model" name is overly generic, ambiguous and somewhat
   misleading, as we usually mean the virtual memory layout/model
   when we say "memory model". GCC too uses it in that sense [...]"

Make it clear that tools/memory-model/ uses the term "memory model" as
shorthand for "memory consistency model" by calling out this convention
in tools/memory-model/README.

Stick to the original "memory model" term in sources' headers and for
the subsystem name.

This directory contains the memory consistency model (memory model, for
short) of the Linux kernel, written in the "cat" language and executable
by the externally provided "herd7" simulator, which exhaustively explores
the state space of small litmus tests.
In addition, the "klitmus7" tool (also externally provided) may be used
to convert a litmus test to a Linux kernel module, which in turn allows
