Konstantin Obenland 8f37374c3d Site Icon: Improvements to Site Icon API.
* Only call `get_blog_option()` when there is a blog id and we're in Mulitsite. If there is no blog id the request is for the current blog.
* Check return value of `wp_get_attachment_image_src()` before getting the URL since it could be `false`.
* Use `{bool}` rather than `!!` to return a boolean value.

Props MikeHansenMe, obenland.
Fixes #33326.
