This continues #23374, which always kept around both attributes, by
always including both propagated files: `propgated-native-build-inputs`
and `propagated-build-inputs`. `nativePkgs` and `crossPkgs` are still
defined as before, however, so this change should only barely
observable.
This is an incremental step to fully keeping the dependencies separate
in all cases.
Oracle JDK 9 does not seems to contain jre directory, so oraclejre9
package now uses a dedicated archive file.
There is no 32-bit version nor arm version (yet). If Oracle releases
them, I will update the package.
