Run QuarkusTestResource in the runtime ClassLoader

[stuartwdouglas]

This is only for QuarkusTest, QuarkusUnitTest will need
a slightly different solution if we decide it is a problem, as
the lifecycles don't match.

Fixes #7880

@lkrzyzanek @aldettinger @andrejpetras any chance you can test this?

[lkrzyzanek]

@geoand how can I get build of this PR? Is there a SNAPSHOT maven build to try?

[geoand]

@lkrzyzanek you will need to build the PR locally and use 999-SNAPSHOT as the quarkus version in your code
