Strip dead per-language .slf entries from gGameLibaries

InitializeFileDatabase, the only reader of gGameLibaries[], is called
nowhere in the tree — VFS replaced this legacy loader. Delete the
7 #ifdef GERMAN/POLISH/DUTCH/ITALIAN/RUSSIAN/FRENCH/CHINESE entries
outright rather than runtime-selecting them.

NPC.h: two commented-out #if defined(CRIPPLED_VERSION)||defined(RUSSIAN)
triplets. AimMembers.cpp: two commented-out #ifdef POLISH character-remap
switch blocks. All already-dead. Verify grep for language macros outside
i18n/ now returns only unrelated hits (filename literal, dev-tool CLI flag,
stray comment, historical prose) — no #ifdef guards left.
