Centralize all the jvmti common test classes

We share many common JVMTI test classes between our various JVMTI
tests. We have always shared them by simply copying the .java files to
any tests that need them. This leads to very large code-reviews and
requires manual work if we ever need to update any of the helper
files.

To ensure everything stays in sync this moves all classes to a single
test/ti-common directory that tests then contain symlinks into.

Test: ./test.py --host
