Customize: Fix selective refresh when customizing the 404 template.

Browse Source 
Overrides the 404 status during partial refresh requests to serve back 200 so that the request is not deemed a failure and invoke the fallback behavior (full refresh).

See #27355.
Fixes #40018.

Merges [40316] to the 4.7 branch.
