#13908 Python: Add API to read well log information

Expose well logs attached to a well path through the Python API. A new
`well_path.well_logs()` returns the list of well logs, and each
`WellLog` gains `channel_names()` and `well_log_data()` for reading
channel names, measured depth, optional TVD MSL/RKB, and channel
values.

The read methods are registered on the abstract `RimWellLog` base
class and use the common `RigWellLogData` interface so they work for
imported, LAS and OSDU well logs alike.
