Load: Disable PHP errors for JSON requests

Browse Source 
Because WP REST API requests aren't identified until `parse_request`, it's impractical to reference the `REST_REQUEST` constant in `wp_debug_mode()`. Instead, it's more helpful to assume that a request wanting a JSON response probably doesn't want PHP errors breaking the response.

Props chrisl27, duanestorey, earnjam.
Fixes #44534.
