[lworld] RFR: 8373622: [lworld] Enabling jimage changes break tests with inMemoryJavaCompiler [v2]

[Coleen Phillimore]

> This change tests the properties: java.test.opts and the property for test.enable.preview (set when test has @enablePreview), and will pass --enable-preview -source 26 to the inMemoryJavaCompiler compiler task.  I don't really like this but the alternative is to do the same thing from all the tests, and pass this down as parameters.  Better alternative ideas are welcome.
> 
> When the jimage code is checked in, a bunch of tests fail because of this problem.
> 
> Testing with tier1-4.
