Calling Python to find all these files is convenient, but error-prone. It's easy to forget to call GN again when adding a file. Each of these calls to Python also adds ~50ms to the run time of gn gen, which is small but adds up.
On my desktop, gn gen drops from 600ms to 150ms, noticeably faster.
This leaves one call to find.py for generating skia.h for fiddle. We're not quite sure how to automate that process to happen entirely inside the :skia.h action while maintaining correct dependencies, so I'm leaving it for now.
