[jdk11u-dev] RFR: 8277992: Add fast jdk_svc subtests to jdk:tier3

[Aleksey Shipilev]

Unclean backport to improve 11u testing. It does not apply cleanly for two reasons:

-  https://bugs.openjdk.java.net/browse/JDK-8265793 is not in 11u yet, and I think it would be cleaner to backport that one *after* this issue;
- https://github.com/openjdk/jdk/commit/1b45bf2d581bf75fabefa13e56ecec6e6ae9036c is not in 11u, and it would be not that relevant after this backport;

The avaiability of catch-all `jdk:tier4` protects us from skipping the tests. If there are test group mistakes that drop some tests from `jdk:tier3`, they would be captured by `jdk:tier4`.

Additional testing:
 - [x] Linux x86_64 fastdebug `jdk:tier3`
