Re-enable single parsing of compiler graphs in native-image for 21.2

GraalVM 21.2-dev at some point introduced a new enhancement (enabled by
default) to avoid parsing compiler graphs twice. This enhancement
however results in increased memory usage at the
moment (oracle/graal#3435) which then results
in Quarkus' Integration Test failures in CI.  In GraalVM 21.2 this
appears to no longer be an issue.
