interpreter: deprecated language args that don't apply to targets

`java_args` is only valid for `jar()` (and `build_target()`, but that's
deprecated), while all other language args are invalid for `jar()`. This
deprecates all of those arguments, that shouldn't be allowed, and
provides useful error messages. As an advantage, this avoids generating
useless `java_static_args` and `java_shared_args`.

In order to get useful error messages for both build_target and
executable + *library, we need to separate LIBRARY and BUILD_TARGET a
bit.
