Subject: [PATCH] Spreadsheet: Expose `.sculpt` and `.hide` attributes behind
 debug option

This commit adds five commonly used internal Sculpt Mode attributes
to the Spreadsheet editor when `--debug-value 4001` is passed in to
assist with development and debugging of issues.

The whitelisted attributes are:
* `.sculpt_mask`
* `.sculpt_face_set`
* `.hide_vert`
* `.hide_poly`
* `.hide_edge`

And are displayed after the other existing debug columns.
