RFR: 8285739: disable EA when both JVMTI and Preview are enabled

Mon May 9 17:29:10 UTC 2022

The fix disables EscapeBarrier and EscapeAnalysis when certain JVMTI capabilities are enabled and --enable-preview.

It restores the same behavior as it was before https://bugs.openjdk.java.net/browse/JDK-8227745 "Enable Escape Analysis for Better Performance in the Presence of JVMTI Agents" is implemented when Continuations are enabled.
