drivers: fuel_guage: Add support for Analog Devices LTC2959

[LostinTimeandspaceYT]

The LTC®2959 is an ultra-low power battery gas gauge
that accurately measures charge, voltage, current and
temperature. Its wide input voltage range and its low
operating current make the LTC2959 suitable for many
applications, including duty-cycled systems that operate
over long lifetime.

This driver integrates with Zephyr’s fuel gauge subsystem to provide access to telemetry data such as voltage, current, temperature, and accumulated charge.

Tested on custom hardware with known RSENSE configuration and verified against datasheet behavior.

It looks like the driver itself is missing.

[LostinTimeandspaceYT]

My apologies. I was pushing the driver itself in a separate commit.

IMHO this should go after #90310 (or at least 12a8422) so things can be tested with the generic example.
