URL: https://github.com/apache/echarts/issues/18192

   ### Version
   
   5.3
   
   ### Link to Minimal Reproduction
   
   _No response_
   
   ### Steps to Reproduce
   
   当使用getDataURL对图表进行svg文本输出时，发现ECharts没有对特殊的符号如<进行转义再输出，导致导出的svg文本出错。
   浏览器打开会显示这样的标识，实际的内容没法渲染出来。

   实际内容如下：因<破坏了xml文档结构。

   当转义后，就正常了。
   <text dominant-baseline="central" text-anchor="start" style="font: normal 
normal 14px Microsoft YaHei" x="30" y="7.5" transform="translate(85 520)" 
fill="#333">&lt;5</text>
   
   ### Current Behavior
   
   未对导出的字符串进行转义。
   
   ### Expected Behavior
   
   需要对导出的字符串包含特殊字符时，转义后再输出。
   
   ### Environment
   
   ```markdown
   - OS:
   - Browser:
   - Framework:
   ```
