feat(editor): add highlighter (#10573)

Closes: [BS-2909](https://linear.app/affine-design/issue/BS-2909/新增highlighter)

### What's Changed!

Currently the highlighter tool is very similar to brush, but for the future, it's a standalone module.

* Added `Highlighter` element model
* Added `Highlighter` tool
* Added `Highlighter` entry to the global toolbar
