/* configUSE_TCB_DATA_GROUP_LOCK enables per-TCB spinlocks to protect TCB-specific
* data such as uxPreemptionDisable. This reduces lock contention compared to using
* the global kernel lock. When enabled:
* - Each TCB has its own spinlock (xTCBSpinlock)
* - vTaskPreemptionDisable/Enable use the TCB lock instead of kernel lock
* - prvYieldCore acquires the target TCB's lock before checking uxPreemptionDisable
* This feature requires portUSING_GRANULAR_LOCKS and multi-core. */
