Backport of improvements in deployment from GF8 concurrency branch

[dmatej]

Backported some cleanups from #24954 + much more rather small cleanups because originally it did not pass QL tests and I spent whole week investigating why it always breaks with every small change until I reached this safepoint.

• Added preInvoke before executing CDI extensions in WeldDeployer - some extensions need it.
• Added logging of ignored empty elements in SaxParserHandler
• Fixed few typos
• DeploymentException is now a standard exception - serialization of stacktraces was revisited in Java 9, so I expect that this is ok.
• RestExtension class was deleted, it is not required any more.
• ACLSingletonProvider - cleanup, revided comments, using ConcurrentHashMap instead of Hashtable
• Fixed NPE in EventListener (noticed once in logs)
• ComponentInvocation now has toString
• Added logs to WeldDeployer, - especially events are interesting
• CommonClassLoaderServiceImpl - removed attempts to load Derby from JDK (was possible in JDK6 which we don't support any more for a while)
• Replaced many @Context annotations with @Inject

Note

• Disable whitespaces when reviewing, it will be more readable

Don't merge it yet, I will yet need to extend the preInvoke-postInvoke range - I rebased the #24954 to this locally and it failed few tests with qualifiers which was possible to fix just by this change. However I still need to find out how large range is required.
