Subject: sim: arm: move arch-specific settings to internal header

There's no need for these settings to be in sim-main.h which is shared
with common/ sim code, so move it all out to a new header which only
this port will include.

The BIT override would be better in the place where it's redefined, so
move it to armdefs.h instead.
