selfhost: add *_Drop wrappers to stdlib types; auto-drop uses _Drop instead of _Free

Browse Source 
- Array.bux, Channel.bux, Set.bux, Map.bux: add *_Drop<T> delegating to *_Free
- hir_lower.bux: Lcx_BuildAutoDropFree searches for _Drop suffix instead of _Free
- Skip direct lowering of generic functions (only monomorphized instances)
