Subject: [PATCH] Revert "gpui: Fix `shape_text` split to support \r\n"
 (#31031)

Reverts zed-industries/zed#31022

Sorry @mikayla-maki, I found that things are more complicated than I
thought.

The lines returned by shape_text must maintain the same length as all
the original characters, otherwise the subsequent offset needs to always
consider the difference of `\r\n` or `\n` to do the offset.

Before, we only needed to add +1 after each offset after the line, but
now we need to consider +1 or +2, which is much more complicated.
