Clean up technical debt in integer indexing Python bindings

[ndgrigorian]

This PR proposes various changes to clean technical debt in the tensor integer indexing Python bindings

_populate_kernel_params is refactored to be more readable, and an axis_end parameter is added to the Python bindings, which aligns with the boolean mask Python bindings and improves the logic.

Additionally, usm_ndarray_take and usm_ndarray_put are renamed to py_take and py_put, respectively. This aligns the two with the other non-constructor bindings (usm_ndarray functions are generally constructors).
