include/exec/memattrs: Add two bits of space to MemTxAttrs
We will need 2 bits to represent ARMSecurityState.
Do not attempt to replace or widen secure, even though it
logically overlaps the new field -- there are uses within
e.g. hw/block/pflash_cfi01.c, which don't know anything
specific about ARM.
