[jdk11u-dev] RFR: 8220744: [TESTBUG] Move RedefineTests from runtime to serviceability

[Goetz Lindenmaier]

I backport this for parity with 11.0.17-oracle.

not moved because not in 11:
test/hotspot/jtreg/runtime/RedefineTests/RedefineDeleteJmethod.java
test/hotspot/jtreg/runtime/RedefineTests/libRedefineDeleteJmethod.c
test/hotspot/jtreg/runtime/RedefineTests/TestMultipleClasses.java

Resolved one Copyright.

Marking as clean.
