Pull Request Overview

This pull request adds comprehensive documentation to the signal test case file (signal_tc.c), providing detailed explanations of test objectives, scenarios, verification metrics, dependencies, and expected results for RT-Thread's signal functionality testing.

Key Changes

Added extensive documentation header (lines 21-128) describing test objectives, scenarios, verification metrics, dependencies, and expected results for all signal test functions
Documentation covers 6 test functions: rt_signal_install_test, rt_signal_mask_test, rt_signal_unmask_test, rt_signal_kill_test, rt_signal_wait_test, and rt_signal_wait_test2

Documentation Issue / 文档问题

English: Line 28 states this test verifies "rt_signal_unmask" but it should be "rt_signal_mask". The function name "rt_signal_mask_test" tests the unmask functionality (when signals are unmasked and should be received), not the mask functionality.

中文：第 28 行说明该测试验证 "rt_signal_unmask" 函数，但应该是 "rt_signal_mask"。函数名 "rt_signal_mask_test" 测试的是 unmask 功能（信号取消屏蔽后应该被接收），而非 mask 功能。

…ng mistakes, and ambiguities in function names. Fixed the issue of grammatical errors in words; changed the variable 'recive_sig' to 'receive_sig'. Originally, rt_signal_unmask_test was testing the masking function of rt_signal_mask, while rt_signal_mask_test was verifying whether signals could be sent correctly during unmasking——the function names were exactly opposite to their functions. Now the two function names have been swapped, and the corresponding comments have also been updated accordingly.After modification, it has been verified that the signal-related utests can be executed correctly.
