Bootstrap/Load: Revert fatal error recovery mechanism from 5.1 to polish for 5.2.

Browse Source 
Due to the high number of follow-up tickets and associated security concerns, it was decided to reschedule the fatal error recovery feature for WordPress 5.2, in order to address these issues properly. The feature will continue to be developed, with iterations being merged into trunk early in the 5.2 release cycle.

Fixes #46141. See #44458, #45932, #45940, #46038, #46047, #46068.
