Message:

Posts, Post Types: Only set default title for custom post types if they have title support.

Previously, the default post title was always set to Auto Draft, regardless of whether the CPT supports a title.

This commit ensures that the default title is present when a CPT has title support, and is an empty string otherwise.

Follow-up to [12987], [49288], [49614].

Fixes #45516.
