refactor(test): move 'TestClass' to 'libanki:testutils'

`com.ichi2.testutils.TestClass`

=>

`com.ichi2.anki.libanki.testutils.TestClass`

No Android/AnkiDroid references allow this to occur

Rationale:
Most of the libanki tests rely on `JvmTest`, which relies on `TestClass`

This is the next step in moving these tests across to `libanki`
which should speed up our test process

Issue 18015
