Support Annotated[..., Field()]

[jonashaag]

sa_column in Annotated is not reflected in the table.

# Has column DateTime(timezone=True)
my_dt_working: date time = Field(sa_column=Column(DateTime(timezone=True)))

# Has column DateTime()
my_dt_not_working: Annotated[
    datetime, Field(sa_column=Column(DateTime(timezone=True)))
]

I'm happy to try to contribute a fix but I'll need some pointer where in the code changes need to be made.
