[Test] create a suitable HotSpot testing group for CVM

[luchsh]

CompoundVM is not and should not be 100% compatible with any existing major OpenJDK specifications, but a suitable sub-set of HotSpot tests to validate VM functionalities is still mandatory.

#109 has a backported gc test, more hotspot tests need to be enabled later

TestG1HeapRegionSize.java fails because G1HeapRegionSize has size restriction in jdk17.

Suggested fix: change test source code

<  * @run main/othervm -XX:G1HeapRegionSize=64m -Xmx256m TestG1HeapRegionSize 33554432
---
>  * @run main/othervm -XX:G1HeapRegionSize=32m -Xmx256m TestG1HeapRegionSize 33554432
