refactor(sdk): tipSearch 全删、歌词解码器归位、IPC 桥移除、api-source 层拆除

- 四平台 tipSearch 全部删除(永不做搜索联想),types 同步去掉 tipSearch 字段
- 歌词解码器归位:kg/krcDecode、tx/qrcDecode、kw/lyricDecode(原 common/ 下三处)
- rendererIpc/ipcNames IPC 桥删除,SDK 纯服务端化
- supportQuality 由各平台 apis 内联导出(sdk/index 汇总),kg/kw/tx/wy 改直连 apis/*,api-source 旧层移除
