feat(core): support copy as image in electron app (#8939)

Close issue [AF-1785](https://linear.app/affine-design/issue/AF-1785).

### What changed?
- Support copy as image in electron app：
  -  Select the whole mindmap if any of the mindmap nodes is selected.
  -  Hide unselected overlap elements before taking a snapshot.
  -  Fit the selected elements to the screen.
  -  Add CSS style to hide irrelevant dom nodes, like widgets, whiteboard background and so on.
     - Due to the usage of Shadow Dom in our code, not all node styles can be controlled. Thus this PR use `-2px` padding for `affine:frame` snapshots.
  - Using electron `capturePage` API to take a snapshot of selected elements.
