Using inFipsSunJsseJvm() causes failures in ESXPackSmokeClientTestCase and MigrateToolTestCase

[jkakavas]

The title is vague as it is not obvious yet what causes this failures. When attempting to do a static import of EsTestCase#inFipsSunJsseJvm() in the two aforementioned classes in order to determine if we're running in Java 8 and in fips mode, the transport client used in the test fails to connect to the node. The TransportClient created, has a TransportClientNodesService that ends up having 0 listed nodes.
The failures are reproducible easily locally. Example failure: https://gradle-enterprise.elastic.co/s/yphikcuckyz5e

The workaround for now is to reimplement inFipsSunJsseJvm() in these two classes until we can figure out what causes the error.

@jkakavas Can you confirm whether the above is still an issue? I cannot find either that method inFipsSunJsseJvm, or a use of EsTestCase#inFipsJvm in either of those classes.

Thia is now irrelevant since the changes introduced in #56526
