[IMP] topbar: improve clear formatting action

Description

With this commit, the clear formatting action does a bit more than clearing the format/style: it also clears merges, conditional formats and table styles.

We kept the old CLEAR_FORMATTING as it was so is doesn't break existing spreadsheet (and the command is still used once), and created a new CLEAR_ALL_STYLING command that clears everything else and dispatches a CLEAR_FORMATTING.
