rABC1e5fc68f200a: [electrum] cleanup ser_to_point

Summary

Use better variable names, split the function from ser_to_point(bytes) -> Point into ser_to_coordinates(bytes) -> (int, int)] and ser_to_point(bytes) -> Point.

This will allow us in future commits to remove some ecdsa import in other modules, to keep implementation details contained in ecc.py.

Depends on D16347

This is split out of D16301

electrum/electrumabc/ecc.py
167 ↗	(On Diff #48296)	It' no longer returning a point but coordinates => ser_to_coordinates is a better name
177 ↗	(On Diff #48296)	I understand why you named it like so but it puzzled me at first, as ecdsa is not a curve but an algorithm so it has no point. Not sure if the "ecdsa python module format" idea can be conveyed with a better name though, so I leave that up to you

electrum/electrumabc/ecc.py
177 ↗	(On Diff #48296)	I agree that the name is pretty bad. I kept it just to make future backports easier, but if we are going to rename the other one this one can get a better name too.

rename ser_to_point -> ser_to_coordinates and ser_to_ecdsa_python_point -> ser_to_point
Use a NamedTuple for the output of ser_to_point (better type-safety than a generic 2-tuple)

This makes this diff much smaller
