8353241: [CRaC] Support ZGC

[rvansa]

During my tests with https://github.com/CRaC/example-spring-boot I could not get the image size as low as with G1, but the presented changes improve the image footprint. As as anecdotal data, the image is 177 MB with G1 while 215 MB with ZGC (fastdebug build, -Xmx1G).
