gh-114071: [Enum] update docs and code for tuples/subclasses (GH-114871) 
Update documentation with `__new__` and `__init__` entries.

Support use of `auto()` in tuple subclasses on member assignment lines.  Previously, auto() was only supported on the member definition line either solo or as part of a tuple:

    RED = auto()
    BLUE = auto(), 'azul'

However, since Python itself supports using tuple subclasses where tuples are expected, e.g.:

    from collections import namedtuple
    T = namedtuple('T', 'first second third')

    def test(one, two, three):
        print(one, two, three)

    test(*T(4, 5, 6))
    # 4 5 6

it made sense to also support tuple subclasses in enum definitions.

gh-109022: [Enum] require names=() to create empty enum type (GH-109048)

creating a new enum class called `bar`.  To create the new but
empty class, use:

    huh = Enum('bar', names=())

gh-108682: [Enum] raise TypeError if super().__new__ called in custom __new__ (GH-108704) 
When overriding the `__new__` method of an enum, the underlying data type should be created directly; i.e. .

    member = object.__new__(cls)
    member = int.__new__(cls, value)
    member = str.__new__(cls, value)

Calling `super().__new__()` finds the lookup version of `Enum.__new__`, and will now raise an exception when detected.

        MASK = 0xff

    ~Flag.MASK is Flag(0)

gh-103596: [Enum] do not shadow mixed-in methods/attributes (GH-103600) 
For example:

    class Book(StrEnum):
        title = auto()
        author = auto()
        desc = auto()

    Book.author.desc is Book.desc

but

    Book.author.title() == 'Author'

is commonly expected.  Using upper-case member names avoids this confusion and possible performance impacts.

gh-100098: [Enum] insist on actual tuples, no subclasses, for auto (GH-100099)

which means either alone or as part of a regular tuple. Other
containers, such as lists, dicts, or namedtuples, will not have auto()
transformed into a value.
