Move Parsoid-specific CSS into a subdirectory

The first two files have been added to the root modules/ directory
via I487095d in 2015. No problem.

Many, many more files have been added via I000b453 in 2022. It's
really hard to tell what is what since then.

I'm not absolutely sure what the naming convention for this folder
should be. Could as well be "localized-styles/" or just "Parsoid/".
