Filtering integration tests based on the underlying architecture

[zakkak]

The mandrel team would like to enable testing on AArch64-based github runners. We have done the necessary changes in our pipelines (see graalvm/mandrel#831) and see that a number of tests fail (mostly due to missing multi-arch containers needed for the testing).

While I believe we should visit each case individually and if possible fix testing on AArch64 for it, I expect this to take quite some time as it's not a high priority. So in the meantime I believe we need a way to exclude some tests depending on the underlying architecture. I see the following options for achieving this (ordered by personal preference):

1. Perform the filtering in the Quarkus IT-harness.
2. Extend https://github.com/quarkusio/quarkus/blob/main/.github/native-tests.json to include the supported architectures (as it does for the OS). The tricky part here is that we would need to re-organize the test groups in order to group them by architecture instead of coverage area.
3. Explicitly disable the tests in the github pipelines using -pl ! or a similar approach.

Thoughts?
