tdf#147453 sw: disable Delete Table functions on tracked deletions

In Show Changes mode, disable "Delete Selected Rows" icons
and the same menu options in the following cases:

- no table selection, but the text cursor in a deleted table row;

- with table selection, all selected cells in deleted table rows.

Disable also "Deleted Selected Columns" and "Delete Table"
icons and the same menu options, when the cursor is there
in a deleted table.

Follow-up to commit c4f6fee3bea0d8618b5815e60304ff9359ccd21c
"tdf#147435 sw: enable Accept Change for table selection".
