feat(editor): add toolbar registry extension (#9572)

### What's Changed!

#### Added
Manage various types of toolbars uniformly in one place.

* `affine-toolbar-widget`
* `ToolbarRegistryExtension`

The toolbar currently supports and handles several scenarios:

1.  Select blocks: `BlockSelection`
2. Select text: `TextSelection` or `NativeSelection`
3. Hover a link: `affine-link` and `affine-reference`

#### Removed
Remove redundant toolbar implementations.

* `attachment` toolbar
* `bookmark` toolbar
* `embed` toolbar
* `formatting` toolbar
* `affine-link` toolbar
* `affine-reference` toolbar

### How to migrate?

Here is an example that can help us migrate some unrefactored toolbars:

Check out the more detailed types of [`ToolbarModuleConfig`](https://github.com/toeverything/AFFiNE/blob/c178debf2d49c40b753e1bcaa6f07270bdde7401/blocksuite/affine/shared/src/services/toolbar-service/config.ts).

1.  Add toolbar configuration file to a block type, such as bookmark block: [`config.ts`](https://github.com/toeverything/AFFiNE/blob/c178debf2d49c40b753e1bcaa6f07270bdde7401/blocksuite/affine/block-bookmark/src/configs/toolbar.ts)

```ts
export const builtinToolbarConfig = {
  actions: [
    {
      id: 'a.preview',
      content(ctx) {
        const model = ctx.getCurrentModelBy(BlockSelection, BookmarkBlockModel);
        if (!model) return null;

        const { url } = model;

        return html`<affine-link-preview .url=${url}></affine-link-preview>`;
      },
    },
    {
      id: 'b.conversions',
      actions: [
        {
          id: 'inline',
          label: 'Inline view',
          run(ctx) {
          },
        },
        {
          id: 'card',
          label: 'Card view',
          disabled: true,
        },
        {
          id: 'embed',
          label: 'Embed view',
          disabled(ctx) {
          },
          run(ctx) {
          },
        },
      ],
      content(ctx) {
      },
    } satisfies ToolbarActionGroup<ToolbarAction>,
    {
      id: 'c.style',
      actions: [
        {
          id: 'horizontal',
          label: 'Large horizontal style',
        },
        {
          id: 'list',
          label: 'Small horizontal style',
        },
      ],
      content(ctx) {
      },
    } satisfies ToolbarActionGroup<ToolbarAction>,
    {
      id: 'd.caption',
      tooltip: 'Caption',
      icon: CaptionIcon(),
      run(ctx) {
      },
    },
    {
      placement: ActionPlacement.More,
      id: 'a.clipboard',
      actions: [
        {
          id: 'copy',
          label: 'Copy',
          icon: CopyIcon(),
          run(ctx) {
          },
        },
        {
          id: 'duplicate',
          label: 'Duplicate',
          icon: DuplicateIcon(),
          run(ctx) {
          },
        },
      ],
    },
    {
      placement: ActionPlacement.More,
      id: 'b.refresh',
      label: 'Reload',
      icon: ResetIcon(),
      run(ctx) {
      },
    },
    {
      placement: ActionPlacement.More,
      id: 'c.delete',
      label: 'Delete',
      icon: DeleteIcon(),
      variant: 'destructive',
      run(ctx) {
      },
    },
  ],
} as const satisfies ToolbarModuleConfig;
```

2. Add configuration extension to a block spec: [bookmark's spec](https://github.com/toeverything/AFFiNE/blob/c178debf2d49c40b753e1bcaa6f07270bdde7401/blocksuite/affine/block-bookmark/src/bookmark-spec.ts)

```ts
const flavour = BookmarkBlockSchema.model.flavour;

export const BookmarkBlockSpec: ExtensionType[] = [
  ...,
  ToolbarModuleExtension({
    id: BlockFlavourIdentifier(flavour),
    config: builtinToolbarConfig,
  }),
].flat();
```

3. If the bock type already has a toolbar configuration built in, we can customize it in the following ways:

Check out the [editor's config](https://github.com/toeverything/AFFiNE/blob/c178debf2d49c40b753e1bcaa6f07270bdde7401/packages/frontend/core/src/blocksuite/extensions/editor-config/index.ts#L51C4-L54C8) file.

```ts
// Defines a toolbar configuration for the bookmark block type
const customBookmarkToolbarConfig = {
  actions: [
    ...
  ]
} as const satisfies ToolbarModuleConfig;

// Adds it into the editor's config
 ToolbarModuleExtension({
    id: BlockFlavourIdentifier('custom:affine:bookmark'),
    config: customBookmarkToolbarConfig,
 }),
```

4. If we want to extend the global:

```ts
// Defines a toolbar configuration
const customWildcardToolbarConfig = {
  actions: [
    ...
  ]
} as const satisfies ToolbarModuleConfig;

// Adds it into the editor's config
 ToolbarModuleExtension({
    id: BlockFlavourIdentifier('custom:affine:*'),
    config: customWildcardToolbarConfig,
 }),
```

Currently, only most toolbars in page mode have been refactored. Next is edgeless mode.
