RFR: 8022547: [verifier] move DefaultMethodRegressionTests.java to jdk

[Kumar Srinivasan]

Hello,

Testing this functionality in langtools does not seem to be the 
appropriate location,
and the teams have decided to move it to jdk/test/vm/verifier, which 
seems to be the
logical place.

I have modified the test to remove testng dependencies, also added a 
variant which
involves loading classes via an URLClassLoader which exposed a test bug 
wrt. the
class.version.major not being correct, therefore it is useful to have 
this variant anyway.
