[RTL] actctx.c: Remove ACTIVATION_CONTEXT_WRAPPED

Browse source 
This structure replaced magic field in wine's ACTIVATION_CONTEXT with a new field MagicMarker in a wrapped structure, with the only difference being the field offset. This is pointless, because it's not used anywhere outside of this file. Also remove the related functions, that were never even used in the first place.
