RFR: 8367372: Test `test/hotspot/jtreg/gc/TestObjectAlignmentCardSize.java` fails on 32 bit systems

[Satyen Subramaniam]

On 32-bit systems, the `test/hotspot/jtreg/gc/TestObjectAlignmentCardSize.java` uses the `ObjectAlignmentInBytes` flag, which isn't supported on 32 bit systems. I'm adjusting this test to require `vm.bits` is 64 as per similar [tests](https://sim.amazon.com/issues/JDK-14885).

Tested on:
* 64-bit: with and without change (passes both times)
* 32-bit: with and without change (fails before, skips after)
Note: seeing some GHA failures, but unrelated to the actual test.
