[libc++][docs] Add missing entry for status pages, fix bad formatting, and deduplicate (#148186)

In a previously PR, the entry for P3491R3 define_static_{string,object,array} was missing.
This patch adds it back.

The number of LWG2687, LWG2709, LWG3315, LWG3395, LWG3987, and LWG4113
were duplicated in the title. It seems better to avoid such duplicates.

Also fixes some formatting to properly use italic and code styles, and
remove one improper leading space from the title of P3682R0 (which
caused incorrect alignment in the generated page).
