[Coroutines][Docs] Remove frame packing as a TODO

This has already been done by @rjmccall in D76526 (49e5a97ec363), and
9514c048d89e. We should remove this from the docs.

 Areas Requiring Attention
 =========================
-#. A coroutine frame is bigger than it could be. Adding stack packing and stack 
-   coloring like optimization on the coroutine frame will result in tighter
-   coroutine frames.
-
 #. Take advantage of the lifetime intrinsics for the data that goes into the
    coroutine frame. Leave lifetime intrinsics as is for the data that stays in
    allocas.
