Bootstrap/Load: Ensure `WP_Fatal_Error_Handler` does not conflict with existing mechanisms treating fatal errors.

Prior to this change, resuming or activating a plugin or theme that is still broken would result in a redirect loop if in recovery mode. If outside recovery mode, it would cause the error template to be displayed.

Furthermore this applies to breaking a plugin or theme when editing from the backend.

Fixes #46045, #46751.
