[FR]: Provide an API for early exit without stacktrace

[rafikk]

What is the current behavior?

AFAIK, there are currently two ways to exit early in an aspect task:

1. Return an exit code from an impl function
2. Call fail to exit with a stack trace

Describe the feature

It would be great if it wre possible to exit early from a nested function call without a stack trace. Ideally this would be possible with a new API accessible via ctx. Perhaps ctx.std.process.exit to mirror the Rust stdlib? Another option would be to mirror BXL's fail_no_stacktrace.

This needs some discussion i believe, currently we use miette crate "attempting" to print prettier errors, but that comes out horribly, we i am thinking of dropping that crate completely. However, i don't have answer for what should replace error handling in axl.
