Anonymous boxes that wrap inlines should not inherit overflow

In legacy layout, anonymous text wrappers were inheriting the overflow
and text-overflow properties. This results in the creation of extra
clipping for these anonymous wrappers which could clip away floats. We
will likely implement text-overflow differently in non-legacy layout.

This change marks all legacy layout pseudo elements as "legacy" and also
adds a new pseudo element for non-legacy layout that does not inherit
overflow.

Fixes #<!-- nolink -->30562.
