Enable UseStringDeduplication where feasible

[schlosna]

OpenJDK 17.0.2 fixed https://bugs.openjdk.org/browse/JDK-8277981 so worth re-testing and consider enabling -XX:+UseStringDeduplication by default when using supported GC on JDK 17+ to both reduce string heap bloat and streamline comparisons in string heavy services.

Reopening as #1452 reverted -XX:+UseStringDeduplication until we can more broadly performance test.

G1 and Shenandoah GC support string deduplication as of JDK 17

https://bugs.openjdk.org/browse/JDK-8264718

Only enable on JDK 17+ due to fix
https://bugs.openjdk.org/browse/JDK-8277981

JDK 18+ enable string deduplication for SerialGC, ParallalGC, and ZGC.
