Newer version of TS is stricter about types and flags counter-variant
types in some situations. This change inlines the DirectiveDefArgs
into the arguments which:
1) removes the inheritance which caused the issue and
2) Makes it more friendly to IDEs since they will not report comments.

Implement NgOnChangesFeature, ViewContainerRef, TemplateRef,
and the renderEmbeddedTemplate instruction, and wire together the
pieces required for the ngForOf directive to work.

This change makes the code cleaner for the user. It does mean
a little bit more work for us since we have to patch the `type` back
into the `DirectiveDef`. However since the patching happens only once
on startup it should not be significant.

We used to have a separate `directive` instruction for instantiating
directives. However, such an instruction requires that directives
are created in the correct order, which would require that template
compiler would have knowledge of all dependent directives. This
would break template compilation locality principle.
This change only changes the APIs to expected form but does
not change the semantics. The semantics will need to be corrected
in subsequent commits. The semantic change needed is to
resolve the directive instantiation error at runtime based on
injection dependencies.
