Database updates and post-updates that throw a PHP \Error are not recorded as failed

Generated with the help of an LLM.

Problem/Motivation

DatabaseUpdate::doOne() and update_invoke_post_update() catch \Exception only. When a hook_update_N() or hook_post_update_NAME() implementation throws a PHP \Error (a TypeError, a call to an undefined function, etc.), it is not logged or recorded in the batch results as an aborted update. It propagates out of the batch, so update.php and CLI runners get a fatal error instead of the usual "Failed: ..." report, and dependent updates are not marked as aborted.

Steps to reproduce

Add an update hook containing throw new \TypeError('x'); and run database updates.

Proposed resolution

Catch \Throwable in both runners. Error::decodeException() already accepts \Throwable, so the logging and #abort handling work unchanged.

API changes

None. Errors thrown by update functions are now reported the same way as exceptions.

Data model changes

None.

User interface changes

None.
