Extend python Enum interop to DataFrame/Series/Enum construction

[deanm0000]

Description

In furtherance of #16858

It seems that if we have

from enum import auto, StrEnum
import polars as pl

class Color(StrEnum):
    red = auto()
    green = auto()
    blue = auto()

that the following should return a column that is an Enum type

df = pl.DataFrame({'color': [Color.red, Color.green, Color.blue]})

should return the color column as a pl.Enum in the same way that pl.lit was made to.

Similarly, we should be able to do pl.Enum(Color)
