This change adds support for `white-space-collapse: break-spaces` and adds initial parsing support for `overflow-wrap` and `word-break`. The later two properties are not fully supported, only in their interaction with `break-spaces`. This is a preliminary change preparing to implement them. In addition, `break_and_shape` is now forked and added to Layout 2020. This function is going to change a lot soon and forking is preparation for this. More code that is only used by Layout 2013 is moved from `gfx` to that crate. Co-authored-by: Rakhi Sharma <atbrakhi@igalia.com>
