Disable remote GDB support by default

The continuous benchmark has been integrated along with recent
improvements for general performance. It's worth noting that remote
GDB support can have a negative impact on instruction execution. To
ensure that the continuous benchmark accurately reflects the
performance metrics, it is advisable to exclude GDB support at the
moment.
