target/m68k: introduce is_singlestepping() function
The m68k translator currently checks the DisasContextBase singlestep_enabled
boolean directly to determine whether to single-step execution. Soon
single-stepping may also be triggered by setting the appropriate bits in the
SR register so centralise the check into a single is_singlestepping()
function.
