Remove dangling WCS references from fenix-dylib megazord

[oskirby]

Description

I was attempting to get a try build going for #7542 and I ran into some difficulty with mach uniffi generate because there seem to be a bunch of dangling references to the worldcup features that got removed in PR #7539, but we seem to have neglected the fenix-dylib megazord that still trys to link them in.
