[libc++] Reword release note section about future releases

[ldionne]

For several releases, we had a section in the release notes that was called "Upcoming Deprecations and Removals". That section was used to advertize breaking changes in future releases as opposed to ones in the current release.

However, the way this section was worded and organized made it unclear what release these announcements related to. This patch rewords that section of the release notes to make it less ambiguous and moves items that aren't done yet (but relate to the ongoing release) to a different section with a TODO.
