[libc++] Remove labels from CSV status pages

We used to provide associate labels to individual rows in the status
tracking CSV files. This was useful to find issues related to a specific
part of the library. However, since we now have Github to track this
information, using labels in the CSV files is not really useful.

Furthermore, keeping the labels synchronized between the CSV files and
the ever-changing Github issues is going to be very challenging.
