This change continues to set up the framework for tracking base measures and computing corrections on transformed densities. In `TransformedDistribution` we update `log_prob` to call a version of `experimental_local_measure` that keeps track of the base measure. We use the backwards-compatibility argument to control this rollout. Note that this change reverses the bijector method called by `transformed_distribution._log_prob` from `inverse_log_det_jacobian` to `forward_log_det_jacobian`, which (i) shifted the numerics, and (ii) affected which functions get exercised by the test suite. As a result, in this change we (i) loosen tolerances in some tests, and (ii) find and fix a dtype correctness bug in `moyal_cdf`. PiperOrigin-RevId: 385616650
