Add new UI gadgets

[agrojean-ledger]

Add two new UI gadgets :

• MultiPageMenu to display menus with pages that can have various styles :

  • PictureNormal : Picture (should be 16x16) with two lines of text (page layout depends on device).
  • PictureBold : Icon on top with one line of text on the bottom.
  • BoldNormal : One line of bold text and one line of normal text on Nano S or up to 3 lines on Nano X/SP.
  • Normal : 2 lines of centered text.

  MultiPageMenu new function takes an io::comm as parameter so its show function can return a page index (in case of user "both button press") or any other event upon reception. It allows for any APDU to be received and processed when a menu is displayed.

• MultiFieldReview to review multiple fields with a review message at the start and validation/cancel messages at the end. The show function returns a boolean upon validation/cancellation by the user.
