This tries to remove includes of "-inl.h" headers from normal ".h"
headers, thereby reducing the chance of any cyclic dependencies and
decreasing the average size of our compilation units.

Note that this change still leaves 5 violations of that rule in the
code. It only tackles "node.h" including "types-inl.h".
