… thumbnails (#6454)

#### What type of PR is this?
/kind feature
/area core
/milestone 2.19.x

#### What this PR does / why we need it:
实现了图片类型的附件缩略图生成和管理的新机制

实现依据 RFC：halo-dev/rfcs#24

使用缩略图前需要配置 externalUrl 才能生成

**How to test it?**
1. 测试本地缩略图的文件是否正确，每个图片对应到相应 size 的目录如 thumbnails/w400 应该是一对一
2. 每个图片生成缩略图的只会在 `http://localhost:8090/apis/storage.halo.run/v1alpha1/thumbnails` 中存在一份记录
3. 测试删除附件会删除对应的缩略图文件和 [thumbnails](http://localhost:8090/apis/storage.halo.run/v1alpha1/thumbnails) 
记录
4. 修改 externalUrl 以上功能均不会受到影响

#### Which issue(s) this PR fixes:
Fixes #2387 

#### Does this PR introduce a user-facing change?
```release-note
附件图片支持生成多尺寸图片，文章支持响应式图片。

#### What this PR does / why we need it:
本次 PR 为本地附件存储策略增加了对上传单文件大小和文件类型限制的功能，具体包括：

1. 单文件大小限制：
实现了对单个文件上传大小的验证功能，确保上传文件不超过设定的最大值。
2. 文件类型限制：
添加了文件类型限制功能，使用 Apache Tika 读取上传文件的 magic numbers 得到文件 mime type 并根据用户配置来决定是否允许上传
