Remove LayoutLibErrorFilterStatement

Paparazzi 2.0.0-alpha05.1 ships layoutlib 16.2.3, which fixes the errors this
rule was swallowing. All screenshot tests pass without it.

- * Workaround for Paparazzi 2.0.0-alpha05 / LayoutLib 16.2.1 bug where
- * HandlerThread_Delegate calls Thread.setPosixNicenessInternal which doesn't exist on JVM.
- * Tracked in https://github.com/cashapp/paparazzi/issues/2342 — fixed in layoutlib 16.2.3.
- * Remove this workaround once Paparazzi ships with layoutlib >= 16.2.3.
- *
- * Paparazzi's PaparazziLogger collects background thread errors and re-throws them via
