🙇  Improve meta data publisher logo behaviour
This is a follow-up PR for #8285.

Reasons: The code changes of #8285 caused error messages when falling back to the default `favicon.ico`, as the `image-size` tool doesn't support `ico` files.

This PR takes the logic to decide which logo needs to be listed in our schema into a new fn `blog_logo.js`. There we have now three decisions:
1. If we have a publication **logo**, we'll take that one
2. If we have no publication logo, but an **icon** we'll use this one.
3. If we have none of the above things, we fall back to our default `favicon.ico`

Additional, we're hard coding image dimensions for whenever the logo is an `.ico` file and built and extra decision to not call `image-size` when the dimension are already given.

I will create another follow-up PR, which checks the extension type for the file and offers it as a util.

🛠  Blog icon util

refs #7688

Serve functionality around the blog icon in its own util:
- getIconDimensions -> async function that takes the filepath of on ico file and returns its dimensions
- isIcoImageType -> returns true if file has `.ico` extension
- getIconType -> returns icon-type (`x-icon` or `png`)
- getIconUrl -> returns the absolut or relativ URL for the favicon: `[subdirectory or not]favicon.[ico or png]`

📖  Get .ico sizes for meta data & logo improvement

refs #7558
refs #8221

Use the new `blogIconUtil` in meta data to fetch the dimensions of `.ico` files.

Improvements for `publisher.logo`: We're now returning a hard-coded 'faked' image dimensions value to render an `imageObject` and prevent error our schema (Google structured data). As soon as an image (`.ico` or non-`.ico`) is too large, but - in case of non-`.ico` - a square format, be set the image-dimensions to 60px width and height. This reduces the chances of getting constantly error messages from Googles' webmaster tools.

- add getIconPath util
