Unexclude com/sun/jdi/RedefineCrossEvent.java on JDK8

[zzambers]

Test com/sun/jdi/RedefineCrossEvent.java should no longer be excluded on JDK 8. It was fixed by:
https://bugs.openjdk.org/browse/JDK-8279669

@zzambers - Can you sign the ECA? https://adoptium.net/docs/eca-sign-off/

@CarmenDelgadoEclipse - this is an example where a Red Hatter (who would be covered under the Red Hat member agreement and should not need to sign the ECA, still needs to in order to pass the ECA validation check). What action could be taken to correct this for others in a similar situation? Does zzambers need to add something to their Github account to indicate they are a Red Hat employee?

Verifying this PR (and that the test runs and passes) in following test runs:
jdk17 x86-64_linux: https://ci.adoptopenjdk.net/view/Test_grinder/job/Grinder/6479
jdk17 aarch64_mac: https://ci.adoptopenjdk.net/view/Test_grinder/job/Grinder/6480
jdk17 x86-64_windows: https://ci.adoptopenjdk.net/view/Test_grinder/job/Grinder/6481

Ignore those, wrong JDK_VERSION, see JDK8

failure on mac looks like infra problem

[smlambert]

Failure on mac was a reviewer error, as we do not have aarch64 mac builds for JDK8, x86-64_mac run looks fine.
