tdf#142763 sc UI: add first page header/footer options

Add checkbox "Same content on first page" checkbox
(similar to the existing "Same content on left and right
pages) to the Page Style dialog window, on the Header
and Footer panes.

Follow-up to commit 19fa853ce12136b5c14e0c5a0aa906c296b75388
(tdf#121715 XLSX: support custom first page header/footer)
and commit 52beb3907dd3c7e6ae112e263def1005272cecd8
(tdf#142764 sc: import "Same content on first/left page").

Note: to set different header or footer on the first page
of the spreadsheet, disable "Same content on first page"
on Format->Page Style...->Header (or Footer), and choose
the "Edit..." button.
