Aileen Nowak b086b432ad Dumped icojs and use image-size for .ico (#8888)
refs #8868

The `image-size` library supports now `.ico` files, which means there is no longer need to use the `icojs` library.
- removes unnecessary `icojs` dependency
- refactors `getIconDimensions` fn in blog icon util to fetch image sizes synchronus
- removes unnecessary `getIconDimensions` fn in blog icon validation, as there is no longer need to use different image size fn for different file extensions, and uses `getIconDimensions` from blog util fn instead.
- updates and adds more tests
