layouts: altcoin apps

[mmilata]

This is a follow-up of #1480 which modifies all altcoin apps to use the layout abstraction. To support various multiple page confirms it adds the paginate_paragraphs function which is a generalization of paginate_text that allows mixing fonts in the paginated output, with the restriction that different font text must start on a new line.

In the previous PR we discussed the truncate= parameter which is used here to emulate the old behavior wrt. text that doesn't fit on a single screen. It's used quite a lot to keep the UI diff small (or skip the pagination logic if we know the text fits), even in some cases where pagination might be desirable. Ideas?

My aim was to keep the UI diff reasonably small even though there are some differences especially for Eos and Monero.

Not covered in this PR, to be done in the next (final) one:

• apps.management and apps.webauthn
• splitting trezor.ui.layouts.tt to multiple modules to make it smaller
• review of br_type values to have them consistent & useful to Suite

Rebased to master. UI diff.

before this is merged, I want to do two things:

• Implement auto-swiping. I'll do that via a separate PR and then rebase this on top of it. This will improve the UI diff, because right now a lot of screens are not correctly scrolled.

• Finish the TODO with putting property label and value always on the same screen

I rebased this on today's master (incl. auto-pagination) and finished the key+value display above.

@mmilata please review my commits (starting at 85cdddc)

Thanks for finishing confirm_properties, it looks very good! Seems like device tests failed, probably due to the ButtonRequest changes. Am curious about the final UI diff, but the screens I've seen look OK.

CI passing now

Reviewed UI diff for the last time and found no regressions, only improvements. Let's merge it.
