This allows users to customise how `Backtraces` are displayed by using a custom implementation of `displayExceptionWithInfo`, overwriting the default implementation for `Backtraces` (`displayBacktraces`). (cherry picked from commit c91e26500ab0e1b8b67c1d374f657523c7c15f55) - - - - - 4758f298 by fendor at 2025-08-18T10:11:01-04:00 Allow users to customise the collection of exception annotations Add a global `CollectExceptionAnnotationMechanism` which determines how `ExceptionAnnotation`s are collected upon throwing an `Exception`. This API is exposed via `ghc-experimental`. By overriding how we collect `Backtraces`, we can control how the `Backtraces` are displayed to the user by newtyping `Backtraces` and giving a different instance for `ExceptionAnnotation`. A concrete use-case for this feature is allowing us to experiment with alternative stack decoders, without having to modify `base`, which take additional information from the stack frames. This commit does not modify how `Backtraces` are currently collected or displayed.
