I mostly have questions about what is missing from this PR. :-) (If this is supposed to remove the final remnants of JNF)

- There is a disabled warning in `make/autoconf/flags-cflags.m4`, line 173, referring to JavaNativeFoundation. It can presumably be removed. If it triggers individually instead, the warning should be disabled on a per-library basis.

- In `make/modules/java.base/Lib.gmk`, line 99 & 113, are references to JavaNativeFoundation. It seems that `libosxsecurity` needs to be cleaned from JNF as well. Also, the comments indicate that the exception for STATIC_BUILD can be removed. (You can verify this with `configure --enable-static-build`)

- In `make/modules/java.desktop/Lib.gmk`, line 129, and `make/modules/java.desktop/lib/Awt2dLibraries.gmk`, line 866 & 094, it seems like `libosx`, `libawt_lwawt`, and `liboxui` also has JNF that needs to be removed. If these are fixed in any of the other issues for the umbrella JDK-8257852, I apologize. I could not figure that out.

- There is also a test dependency that I have seen being addressed, in `make/test/JtregNativeJdk.gmk` line 82, for `libTestMainKeyWindow`.
