libstdc++: Update C++20 library status docs
This reorganises the C++20 status table, grouping the proposals by
category. It also adds more proposals, and documents all the feature
test macros for C++20 library changes.
* doc/xml/manual/status_cxx2020.xml: Update C++20 status table.
* doc/html/*: Regenerate.
