Investigate how to turn off Godot crash handler

[limbonaut]

We need to find a way to turn off Godot crash handler when Sentry SDK is active as it may cause issues.

Users can use --disable-crash-handler command-line option as a workaround. It's better if we automate crash handler unregistration, though. Currently, there is no API that allows us to do this.
