Remove duskscriptvm.h, fold its includes into script.h

It had exactly one consumer (script.h) and added nothing of its own beyond
re-including duskscript.h + image/scriptvmattach.h + image/scriptvmrun.h -
a pointless indirection now that it's not a standalone embedding SDK with
multiple external consumers.
