Add missing TUs for Wii/Shield retail (+ filename cleanup) (#3072)

* Fix GCN_mem_alloc.c filename capitalization * Fix up TRK file names in Wii/Shield splits * Add string_TRK * Add cc_gdev * Add Shield-only wstring TUs * Implement NdevExi2A * Add missing JSystem TUs (more are still missing from ShieldD) * Clean up includes
