Scan GX_DEFERRED overrides, and guard the Retro-WFC payload

The native-registration scan only knew PPC_NATIVE_OVERRIDE, so every
GX_DEFERRED_OVERRIDE_VOID was missing from the index; the deferred form
registers `symbol` and posts the hand-written `symbol_gx`.

A Retro Rewind kit built from a translation without the Retro-WFC payload now
refuses to package instead of crashing on entering WFC, and on Android ImGui
keeps off SDL's cursor, which ART aborts on from a guest fiber's stack.
