/**
* Test Case Name: Kernel Core Mailbox Performance Test
*
* Test Objectives:
* - Measures mailbox object synchronization performance
* - Validates mailbox message passing with priority handling
* - Provides latency metrics for inter-thread communication
*
* Test Scenarios:
* - **Mailbox Message Passing**: Single message (1) sent/received
* - **Priority Handling**: Higher-priority thread (THREAD_PRIORITY+1) response
* - **Stress Test**: Repeated message passing (RT_UTEST_SYS_PERF_TC_COUNT times)
* - **Thread Coordination**: Two threads exchanging messages via semaphores
*
* Verification Metrics:
* - Message passing latency < 40μs
* - 0 errors in mailbox operations
* - Consistent results across test cycles
* - No memory leaks during test
*
* Dependencies:
* - RT_USING_MAILBOX must be enabled
* - RT_USING_UTEST framework
* - Hardware timer support (for high-precision timing)
*
* Expected Results:
* [ PASSED ] [ result ] testcase (core.mbox)
* - Structured performance data table (Min/Max/Avg latency)
* - Final line: "=== Mailbox Performance Test Results End ==="
* - Executable via: `utest_run core.mbox` in msh
