sim: cr16: 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 drop the cr16_sim.h include and move it to
the few files that actually need it.

Also rename the file to standardize it a bit better with other ports.
