travis: enable test suite on ARM64 (#20219)

* travis: Enable ARM support * Include fixes from 20039 * Add a trace to debug the invalid lookup issue * Try increasing the timeout to see if the arm test passes * Investigate the resolver issue * Increase arm64 timeout for clique test * increase timeout in tests for arm64 * Only test the failing tests * Review feedback: don't export epsilon * Remove investigation tricks+include fjl's feeback * Revert the retry ahead of using the mock resolver * Fix rebase errors
