Add missing configuration macros to FreeRTOSConfig.h template

[anand16158]

Add 16 documented configuration macros to the existing `FreeRTOSConfig.h` template in `examples/template_configuration/`. These macros are supported by the kernel but were not represented in the template.

Macros added

Scheduling / Tick:

• `configINITIAL_TICK_COUNT` - initial tick counter value (useful for overflow testing)
• `configEXPECTED_IDLE_TIME_BEFORE_SLEEP` - minimum idle ticks for tickless mode
• `configPRE_SUPPRESS_TICKS_AND_SLEEP_PROCESSING` (commented)
• `configPRE_SLEEP_PROCESSING` / `configPOST_SLEEP_PROCESSING` (commented)
  Task / Debug:
• `configRECORD_STACK_HIGH_ADDRESS` - debugger backtrace support
• `configRUN_TIME_COUNTER_TYPE` - run-time stats counter type
• `configPRINTF` - application printf wrapper (commented)
  TLS / C Library:
• `configUSE_PICOLIBC_TLS` - picolibc TLS integration
• `configUSE_C_RUNTIME_TLS_SUPPORT` - generic C runtime TLS
  ARM / FPU:
• `configUSE_TASK_FPU_SUPPORT` - per-task FPU context management
  Misc:
• `configINCLUDE_FREERTOS_TASK_C_ADDITIONS_H`
  INCLUDE_ API toggles:*
• `INCLUDE_uxTaskGetStackHighWaterMark2`
• `INCLUDE_xQueueGetMutexHolder`
• `INCLUDE_xSemaphoreGetMutexHolder`
• `INCLUDE_xTimerGetTimerDaemonTaskHandle`

Context

Follows feedback from FreeRTOS/FreeRTOS#1402 (now closed) where a maintainer directed that additions to the config template should go in this repository.
Refs FreeRTOS/FreeRTOS#65

Test Steps

1. Copy the updated template to a demo project as `FreeRTOSConfig.h`.
2. Build for a 32-bit target (e.g. Posix_GCC or Cortex-M) — no new compiler errors or warnings.
3. Verify all newly added macros are set to safe defaults (0 or commented out)."
