plugins: ledger: rm support for hw.1

This removes support for Ledger HW.1 and "Nano" (non-S) devices.
These were manufactured/sold around 2015-2016, and are long unsupported by the upstream vendor.

We previously added a deprecation warning to the GUI [0] released in 4.3.3 (2023-01-02), to warn owners of these devices.
This PR now fully removes support.

As a consequence, the unmaintained btchip-python dependency can now be removed, which solves [1].
