  [IFC] Add simplified minimum width support for non-text content
https://bugs.webkit.org/show_bug.cgi?id=265177

Reviewed by Antti Koivisto.

Let's expand simplified minimum width computation (where we can break at arbitrary position) to non-text content.

1. Check for nested content eligibility (e.g. <div>eligible content<span style="white-space: pre">not eligible content</span></div>)
2. Compute simplified minimum width on non-text content.
