Extend literal with date, datetime and time

[Fokko]

Feature Request / Improvement

The date, datetime and time is currently not supported as literal value:

>>> from datetime import date
>>> literal(date(2023, 1, 1))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/fokkodriesprong/Desktop/iceberg/python/pyiceberg/expressions/literals.py", line 148, in literal
    raise TypeError(f"Invalid literal value: {repr(value)}")
TypeError: Invalid literal value: datetime.date(2023, 1, 1)

We need to accept those as literal:

• datetime If there is a timezone, we want to convert it to a timestamptz. We can convert the datetime to an integer using datetime_to_millis in datetime.py.
• time We can convert this into an integer using time_to_micros from datetime.py
• date We can convert this into an integer using date_to_days from datetime.py

And include tests that hit the newly created branches in the if.
