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.

此 issue 針對 Angular CLI 的 build 命令，並參考了 unjs/fontaine Vite 外掛程式和 seek-oss/capsize 的 CSS 產生。先閱讀這些參考內容，然後確定 CLI 整合範圍；完成的條件應是提供內建的字型大小調整支援，但未指定檔案、測試或驗收標準。
