accel/tcg: Report one-insn-per-tb in 'info jit', not 'info status'

Currently we report whether the TCG accelerator is in
'one-insn-per-tb' mode in the 'info status' output.  This is a pretty
minor piece of TCG specific information, and we want to deprecate the
'singlestep' field of the associated QMP command.  Move the
'one-insn-per-tb' reporting to 'info jit'.

We don't need a deprecate-and-drop period for this because the
HMP interface has no stability guarantees.
