Detailed Description

Eclipse ThreadX user-tunable defines for ra8-firmware.

Picked up by both the ThreadX library build and the application TUs because the project compiles ThreadX with TX_INCLUDE_USER_DEFINE_FILE and adds port/threadx/ to the include search path.

Tunables intended for the RA8 family:

TX_TIMER_TICKS_PER_SECOND = 1000 – 1 ms tick. SysTick reload is programmed in tx_initialize_low_level.S to match.
TX_MINIMUM_STACK = 512 – doubled from upstream (200) to give floating-point + Helium register save plenty of room.
TX_MAX_PRIORITIES = 32 – single 32-bit priority bitmap word, the minimum legal value and the fastest path through the scheduler.
TX_TIMER_PROCESS_IN_ISR – run timer expiration directly from the SysTick ISR. Saves the timer-thread context switch.
TX_REACTIVATE_INLINE – inline timer reactivation; small speedup for periodic timers that only matters once we have a real workload.
TX_DISABLE_PREEMPTION_THRESHOLD – the demo does not use it; saves code size.
TX_DISABLE_NOTIFY_CALLBACKS – ditto.

Single-mode-secure: this firmware runs Secure-only for now (Cortex-M85 TrustZone is configured but no Non-Secure partition is loaded), so we tell ThreadX it can skip the secure-stack management code.
