cointool: replace 'coins_json' with 'dump'

Browse Source 
`cointool.py coins_json` generated an old-style `coins.json` file with
entries on bitcoin-like coins. This is no longe really doing what we
need.

Instead, the new command `dump` will output _all available data_ in the
same format as Python sees it. Much more useful for other kinds of
consumers.

* **`check`**: check validity of json definitions and associated data. Used in CI.
* **`coins_json`**: generate `coins.json` file for use in Connect, webwallet and python-trezor.
This file contains data on Bitcoin-like coins and their support status.
* **`dump`**: dump all coin information, including support status, in JSON format.
* **`coindefs`**: generate signed protobuf descriptions of coins. This is for future use
and could allow us to not need to store coin data in Trezor itself.
