Add built-in support for font size-adjustment

### Command

build

### Description

As mentioned in https://github.com/angular/angular-cli/issues/27038#issuecomment-1935614283 the Aurora team strongly recommends addressing size-adjustment directly within the Angular CLI.

They've collaborated with the Nuxt team to develop a Vite plugin that automatically calculates CSS adjustments for size, which you can find here: https://github.com/unjs/fontaine. Additionally, this functionality is available through CSS generation: https://github.com/seek-oss/capsize.

该 issue 针对 Angular CLI 的 build 命令，并引用了 unjs/fontaine Vite 插件和 seek-oss/capsize 的 CSS 生成。先阅读这些引用内容，然后确定 CLI 集成范围；完成的标准应是提供内置的字体大小调整支持，但未指定文件、测试或验收标准。
