REST API: Shim post_date_gmt for drafts / empty dates in the REST API.

Internally, WordPress uses a special post_date_gmt value of 0000-00-00 00:00:00 to indicate that a draft's date is "floating" and should be updated whenever the post is saved. This makes it much more difficult for API clients to know the correct date of a draft post.

This commit provides a best guess at a date_gmt value for draft posts in this situation using the date field and the site's current timezone offset.

Props joehoyle.
Fixes #38883.
