The point of qtest is to simulate how running code might interact with
the system. However because it's not a real system we have places in
the code which especially handle check qtest_enabled() before
referencing current_cpu. Now we can encode these details in the
MemTxAttrs lets do that so we can start removing them.

v2
  - use a common macro instead of specific MEMTXATTRS_QTEST
v3
  - macro moved to earlier patch
