RFR: 8273774: CDSPluginTest should only expect classes_nocoops.jsa exists on supported 64-bit platforms [v5]

[Remilia Scarlet]

> The test assumes that it always runs on 64-bit platform and classes_nocoops.jsa is always created.
> It's a test bug. The test should only expect classes_nocoops.jsa exists if it's running on a supported 64-bit platform.
> However, for unknown target platform, it's unknown if it's 64-bit or not.
> 
> This patch fix the test to check if classes_nocoops.jsa exists only on one of the JDK supported platforms (x64 or aarch64) via the sun.arch.data.model system property.
> 
> Please review this change. Thanks!
