Reviewed by Alexey Proskuryakov.

As of 278812@main, generate_xcfilelists_lib is using WK_PLATFORM_NAME,
which means it needs to handle Mac Catalyst. Add it as a supported
platform. In practice this does not change xcfilelist contents, since
the generator was already running in Catalyst builds, it was just
considering them to be the "macosx" platform.
