feat(editor): show doc title in page block (#9975)

Close [BS-2392](https://linear.app/affine-design/issue/BS-2392/page-block-需要显示文章title)

### What Changes
- Add `<doc-title>` to edgeless page block (a.k.a the first page visible note block)
- Refactors:
  - Move `<doc-title>` to `@blocksuite/affine-component`, but you can aslo import it from `@blocksuite/preset`
  - Extract `<edgeless-note-mask>` and `<edgeless-note-background>` from `<affine-edgeless-note>` to a seperate file
  - Rewrite styles of `<affine-edgeless-note>` with `@vanilla-extract/css`
