add TCK tests for auto-closeable beans (@AutoClose)

[Ladicek]

Fixes #700

[Ladicek]

This is no longer a draft for 2 reasons because:

• the PR includes commits from add TCK tests for eager initialization (@Eager) #659 (because it's a lot easier to avoid conflicts)
• there are no tests for the Producer part of Portable Extensions

Other than that, it should be fine. Submitting it now for @manovotn's ongoing work.

[Ladicek]

Added tests for Producer, but note I didn't run them, because they only make sense for CDI Full.

[Ladicek]

Added a test that the call to AutoCloseable.close() during bean destruction is not a business method invocation. This is ready now.

The commits in this PR could be squashed, but don't necessarily have to be; I don't mind.

[Ladicek]

Rebased, this can be merged now as there's no SNAPSHOT dependency anymore. Of course, after it's reviewed :-)

[Ladicek]

Added one more commit that tests that auto-closeable dependent objects are closed when the containing bean is destroyed.
