rABC597ca78e92c1: [electrum] move-only: move helper functions to avoid libsecp dependency

Summary

This moves helper classes and helper functions to other modules to avoid introducing a dependency on cryptography code for the get_merkle_root.py script. This means we can continue using the script without unnecessarily compiling libsecp256k1.

Now interface.py no longer depends on libsecp, and a helper function was moved from network.py to networks.py because the latter also does not depend on libsecp.

Test Plan

python test_runner.py

With libsecp256k1.so.0 missing:

scripts/get_merkle_root.py

electrum/electrumabc/json_util.py
57 ↗	(On Diff #49872)	All this stuff is only used in interface.py so I moved it there
electrum/electrumabc/networks.py
220 ↗	(On Diff #49872)	I moved parse_servers here because it uses a constant from this module, so it makes sense. Alternatively it can be moved to util.py, but then util will depend on networks.py which could cause circular imports, so maybe it would need its own network_util.py module.
