Add revision tracking for Quick Edit updates in WordPress core

[wprashed]

Enhances the edit_post() function to create revisions for changes made via the Quick Edit feature in the WordPress admin. This ensures that updates performed through Quick Edit are tracked as revisions, allowing users to revert changes if necessary.

Key changes:

• Added a check for the _inline_edit field in $_POST to detect Quick Edit usage.
• Ensured revisions are only created for post types that support revisions.
• Included validation to confirm the post exists before attempting updates.
• Used wp_save_post_revision() to save revisions for Quick Edit updates.

This improvement enhances data integrity and provides better traceability for admin post updates.
