RFR: 8277992: Add fast jdk_svc subtests to jdk:tier3

[Aleksey Shipilev]

OpenJDK tiered tests definitions have the catch-all `tier4` that runs all tests not defined in the lower tiers. `hotspot:tier4` has lots of them, mostly long-running vmTestbase tests, which take many hours even on a very parallel machines.

This, unfortunately, has a chilling effect on `jdk:tier4`, which is seldom run by contributors, because `hotspot:tier4` is in the way. But, there are plenty of fast and stable tests in `jdk:tier4` that can be run in `jdk:tier3`. `jdk_svc` is the example of such tests: management features (including but not limited to JFR) are important to keep from regressions, and significant subset of them runs pretty fast.

So, it makes sense to move some `jdk_svc` tests to `jdk:tier3` to expose it to more contributors. I think the only group we don't want to run is `svc_tools`, which includes lots of non-parallel tests that are rather slow.
