refactor(lex_parser): 移除旧的词法解析器实现并更新依赖

Browse Source 
移除了 libs/lex_parser 目录下的所有头文件和源文件，包括：
- lex_parser.h 和 lex_parser.c 核心解析功能
- 所有测试文件（test_char.c, test_identifier.c, test_number.c,
  test_skip_block_comment.c, test_skip_line.c, test_string.c）

更新了 lexer 模块的依赖配置，将 lex_parser 替换为 sstream，
同时更新了 lexer.h 中的相关包含头文件和数据结构定义，
简化了 scc_lexer_t 结构体的字段。
