soc/intel/pantherlake: Disable stack overflow debug options

This patch disables the `DEBUG_STACK_OVERFLOW_BREAKPOINTS` and
`DEBUG_STACK_OVERFLOW_BREAKPOINTS_IN_ALL_STAGES` Kconfig options
for the Pantherlake SOC.

These options are causing false positive stack overflow detections,
leading to unnecessary debugging.

w/o this patch:

stack corruption before for verstage and romstage early.

Failed to create address zero instruction fetch breakpoint
    Failed to create stack canary breakpoint
    ...
    ...
    Stack corruption detected at rip: 0xf983007a
    Stack corruption detected at rip: 0xf983007a
