Update bundles depending on Java 17 bundles to Java 17

[iloveeclipse]

• used default PDE quickfixes
• updated pom versions manually
• bumped test bundle versions manually
• bumped feature versions manually
• changed buildExtraJAR.xml to use 1.7 as compilation target (jsr14 is not supported anymore)
• changed buildExtraJAR.xml to use zip instead of jar to create snippetsupport.jar (avoids creating useless and ever changing manifest)

This commit requires a fix for
#217 (because of the hard coded line 28 in filterDebugEvents() method in JavaSnippetEditor.java).

Fixes #210

TODO:

1. Tests update to Java 17
2. Fix for org.eclipse.jdt.debug.ui/snippetsupport.jar, if rebuilt, breaks snippet editor #217 (I know how to fix, just need to be properly prepared)

[iloveeclipse]

Note: all tests are green, even if snippet editor evaluation is broken:

Now after rebase on #220 one test will fail.

As expected:

junit.framework.ComparisonFailure: Editor should show evaluation result expected:<2 + 2[(int) 4]> but was:<2 + 2[]>
	at junit.framework.Assert.assertEquals(Assert.java:100)
	at junit.framework.TestCase.assertEquals(TestCase.java:253)
	at org.eclipse.jdt.debug.tests.ui.JavaSnippetEditorTest.testEvaluation(JavaSnippetEditorTest.java:100)

Fix follows soon.
