[jdk11u-dev] RFR: 8183374: Refactor java/lang/Runtime shell tests to java

[Goetz Lindenmaier]

I backport this for parity with 11.0.21-oracle.


The tests were added by "8225054: Compiler implementation for records " after 11
Thus they are not in 11 yet and patching failed.
I include the full tests as in 17 after this change. I think they are useful for 11, too. 
Both pass.
