Backtraces performed by GDB on any thread other than the current thread would fail if hardware 8 byte ISR stack alignment was enabled on cortex_m targets. Stack reads now adjust the stored SP to account for a potential offset introduced by hardware. Fixed incorrect register offsets for cortex_m Nuttx frames by reading the TCB info symbols to determine correct offsets. Fixed offsets can no longer be used since the offsets have changed multiple times for different Nuttx versions. Tested on nuttx-12.1.0. Tested using custom stm32h7 board and custom s32k148 board variants. Built with CONFIG_ARCH_FPU enabled and disabled to test FPU and non FPU frame logic.
