Extend the MemTxAttrs to include 'debug' flag. The flag can be used as
general indicator that operation was triggered by the debugger.
Later in the patch series we set the debug=1 when issuing a memory access
from the gdbstub or HMP commands. This patch is prerequisite to support
debugging the encrypted guest. If we see request with debug=1 then we
will need to use encryption APIs to access the guest memory.
