Add RegLoadAppKeyW

Also, fix source compatibility with Java 6. It blocks my local test run.

Thank you - looks sane to me. I left an inline comment about the naming of the function and please remove the darwin-aarch64.jar.

And one additional request: Please add a feature entry for the newly bound function in CHANGES.md.

@matthiasblaesing Do I need to add the registryLoadAppKey method in CHANGES.md or Advapi32.RegLoadAppKey is enough?

[matthiasblaesing]

I would mention both. If space is an issue the prefix com.sun.jna.platform. is commonly shorted to c.s.j.p..

@matthiasblaesing, it is ready.

Code change looks good. Last change request: Please rebase the changes onto current master. Sunday night the 5.9.0 release was cut. The git diff does not recognize the merge conflict, but it needs to be resolved (merging as is would add the change description to 5.9.0, but it will become part of 5.10.0).

[matthiasblaesing]

Sorry, the CHANGES.md is still wrong. The new change log entry is in the section for the released 5.9.0 version, but should be in the features subsection of the "Next Release (5.10.0)" section.

@matthiasblaesing I misunderstand it, sorry. I updated CHANGES.md

Looks good to me. Thank you.
