[BS-3517](https://linear.app/affine-design/issue/BS-3517/微软新注音输入法无法使用markdown语法)
This PR refactor the markdown transform during inputting, including:
- Transfrom markdown syntax input in `inlineEditor.slots.inputting`,
where we can detect the space character inputed by IME like Microsoft
Bopomofo, but `keydown` event can't.
- Remove `markdown-input.ts` which was used in `KeymapExtension` of
paragraph, and refactor with `InlineMarkdownExtension`
- Adjust existing `InlineMarkdownExtension` since the space is included
in text.
- Add two `InlineMarkdownExtension` for paragraph and list to impl
Heading1-6, number, bullet, to-do list conversion.
Other changes:
- Improve type hint for parameter of `store.addBlock`

### TL;DR
Refactored the BlockSuite turbo renderer to use a hierarchical tree structure for layouts instead of a flat list, improving rendering accuracy and performance.
### What changed?
- Redesigned the layout system to use a tree structure (`ViewportLayoutTree`) that better represents the document hierarchy
- Added `blockId` to all layout objects for better tracking and debugging
- Updated the layout query mechanism to work with models directly instead of components
- Enhanced error handling with more descriptive warnings and error messages
- Improved the painting process to traverse the layout tree recursively
- Fixed viewport coordinate calculations for more accurate rendering
- Updated the worker communication to support the new tree-based layout structure
### Why make this change?
The previous flat layout structure didn't properly represent the hierarchical nature of documents, leading to rendering issues with nested blocks. This tree-based approach:
1. Better represents the actual document structure
2. Improves rendering accuracy for nested elements
3. Makes debugging easier with more consistent block identification
4. Provides a more robust foundation for future rendering optimizations
5. Reduces the likelihood of rendering artifacts when scrolling or zooming
