feat(FormField): Support error icons

### Feature Description

Material Design 3 guidelines [recommend showing an error icon when a text field is in an error state](https://m3.material.io/components/text-fields/guidelines#:~:text=It%E2%80%99s%20strongly%20recommended,additional%20sensory%20indicator.). However, there is no [such example in the Form Field documentation](https://material.angular.dev/components/form-field/examples) and no references to this in the overview section of the documentation.

If this is supported, it should be a added to the documentation. If not, support should be added.

### Use Case

_No response_

先查看 issue 中引用的 Form Field 文档示例和概览，然后检查现有的错误状态行为，以确定是否已经支持错误图标。如果当前组件无法提供错误图标，则应先添加支持再记录；完成的标准是记录一个可正常工作的错误图标示例和概览引用。

由索引模型根据 Issue 内容生成。
