tdf#154270 Sync toolbar button recent colors

As the last used color is stored per button instance, these
will go out of sync with several buttons being visible (e.g.
a toolbar and a sidebar, or a toolbar overflow popup), and
will reset whenever the toolbar resets (e.g. change in
selection, switch from print preview, or customization).

Fix that by storing the last colors per-document, and
notifying other buttons on changes. Keep the last color also
stored per-button for now, as a fallback for reportdesign
(which isn't sfx2 based).
