Report Godot errors with a script stack trace

[limbonaut]

It would be nice to have errors reported with a timestamp that happened prior to a crash or event.

Logging is managed by https://github.com/godotengine/godot/blob/master/core/io/logger.h
This functionality is not exposed in Godot API, and as such cannot be used in GDExtension/GDScript.

AFAIK, there are two PRs possibly landing in Godot that expose logging:

• Add user-facing log interception callback. godotengine/godot#87576
• Add Logger and ability to print and log script backtraces godotengine/godot#91006

For the time being, we can explore a log-based parser and see how performant such approach can be.

UPDATE:

• PR feat: Support for logger, script stack traces, local variables in Godot 4.5 #201

[limbonaut]

We have an intermediary solution in place. Waiting for logging to be exposed in the Godot Engine API.
