set default compatible cds alignment to auto for arm64

Bug: https://bugs.openjdk.org/browse/JDK-8334895
Last-Update: 2024-06-25

ARM64 requires cds alignment option to be enabled if CDS is enabled.
Setting it to true will enable the option even if CDS is disabled
causing a configuration error. Setting option to auto allows one to
enable it only when CDS is enabled.
