RFR(M): 8199252: [TESTBUG] Open source VM testbase system dictionary tests

[Mikhailo Seledtsov]

Please review this change open sourcing VM system dictionary tests. 
These tests have been used internally for a while, and are now being 
open sourced.
Since this is not an creation of new tests, simply open sourcing 
existing tests, we would like to keep the changes during this review to 
an absolute required minimum. If you have any feedback on improvements 
of these tests, please file RFE(s) that will be addressed later in order 
of priority.


Here is what was done for this change:
   1. Moved the tests to OpenJDK repository preserving relative 
directory location and structure.
   3. Updated Copyright statements accordingly.
   4. Updated "@library" statements accordingly.
   5. Updated TEST.groups
