Tests: move more diagnostic tests to testsWithJvmBackend

In this commit, tests where backend diagnostics were reported correctly
are being moved.

FirScopeDumpHandler was added to FIR diagnostic tests with JVM backend
to support `SCOPE_DUMP` in `overridesBuiltinNoMagic.kt` and
`charAtAndOverload.kt`.
