Convert java tests to NewTestArchContext

Java tests will need to test code inside if ctx.Device() blocks,
switch to using TestArchConfig and NewTestArchContext.

Disable TestSdk for now, just registering modules that depend
on the SDK triggers panics because of previously untested code
that is now executed.

Test: java_test.go
