Backporting JDK-8334010: VM crashes with ObjectAlignmentInBytes > GCCardSizeInBytes. This change makes VM initialization reject invalid combinations of ObjectAlignmentInBytes and GCCardSizeInBytes. ObjectAlignmentInBytes larger than GCCardSizeInBytes causes issues with setting correct BOT offsets. Ran GHA Sanity Checks, local Tier 1 and 2, and new test directly. Patch is clean.
