gdb/arm: Update the value of active sp when base sp changes
For Arm Cortex-M33 with security extensions, there are 4 different stacks pointers (msp_s, msp_ns, psp_s, psp_ns). When plain "sp" is updated during unwinding of the stack, the active stack pointer of the 4 stack pointers needs to be kept in sync.
